This scene was created as a "best case scenario" since if there's one place for me to be optimistic, it's in my artwork. There's no guarantee if anything's living there at all and we won't find out whether or not there is for a long time. But it's the best candidate out of all the planets found so far.
Kepler 186f orbits around a star much smaller, cooler and dimmer than our own sun, so the habitable zone where temperature is just right is much closer in, making its "year" only 130 Earth-days long. The weaker sunlight intensity would mean a few things for the surface assuming there is life there. There could be some massive ice caps near the polar regions, as represented in one of the official artist renditions of the planet as it appears from space. Plant life would have to be pretty cold-tolerant so I went with tree types more akin to those found in boreal forests, but tried to put an alien twist on them. The "pine" trees have their needles pointing downwards underneath a woody cap at the end of each branch. This is to shield the needles from excessive snow build-up that's bound to happen at times on a planet which is likeley a cool-temperate climate even nearer the equator. The vegetation colour is mostly black, brown and dark grey rather than green, as plants try to absorb all wavelengths of light to make the most of what they can get from a dimmer sun.
The blackness of the vegetation could also help keep the area immediately around them warmer as dark colours absorb heat, as well as light. This could also be a clever evolutionary way of plants melting off left over snow quicker so they can resume growing. But snowfall could just be up to the daily weather, and not part of a regular seasonal cycle like on Earth, as Kepler 186f is likeley to not be as tilted on its axis as Earth, seasonal variations, if any - probably aren't as extreme as those on Earth. This is because the planet is pulled into line by its close distance to its sun, which tends to keep planets spinning more "upright". This close proximity to its sun also means it likely has no moons and thus no tides or night-time sources of light either. The colour, density and temperature of the atmosphere is not known, but this bronze-ish "afternoon glow" even during midday seems to be a popular candidate, so I went with that

Since planet earth is our only reference, any idea about alien organisms and alternative evolution will remain conjectural, at least for a long time. But we can dream and your picture looks quite realistic. I like it.
By the way, I made a try as well, and have just posted my vision of the alien life of Europa's inner ocean, with an exploration narrative.
I agree that the 6-limbed Avatar animals were indeed disappointing and that evolution would never have shaped so dysfunctional beings. However insects have 6 legs and spiders 8, and they are very functional. Concerning soft-bodied organisms, some deep-sea sea cucumbers have a number rudimentary legs (8, 10, 12, depending on the species). I have seen videos of them moving on the deep-sea mud. They are really functional. The real point is that it's very hard to imagine what evolution would have done, if it had started from something a bit different from what we know. And inversely, some organisms of planet Earth like starfishes have a so strange anatomy that, if they did not exist here, no science-fiction author would have been crazy enough to imagine something like that.
I like how the mid afternoon glow looks kind of like a lovely evening all the time. I guess it helps make the picture more serene in a way. The waterfalls thundering before the ice caps though is the icing on the cake though that really brings the piece together.
I've seen similar lighting situations to this before. In Australia we get pretty severe bushfires every summer. If a layer of smoke from a far away fire makes it over the city the sky turns this colour and the sun glows a bright orange as opposed to the blinding white one would expect it to be in the middle of the day. It makes your shadow appear blue-ish too since the light hitting everything else is sorta orange-filtered. Very surreal when it happens and it's about as close as you can get to see what this world would look like under a red dwarf star.
but if the animals there were anything like here, then yeah, camo white'd be a good option. and maybe dark blue too - is there actually a real pigment for pure black talking about living beings?
anyways, lol, B/W animals'd be fun, like, they couldnplay chess. predator chess, where you lose = you get eaten
unusual.. amanita: check, probably many blue beings (makes me think of cyan - cyanide, eewww)... i wonder how other species more concerned with eating them actually see the colors of poisonous things - that might even not be poisonous to them
