Dragon tan

Poor Ash, she's in for quite the treatment. It's a shame her scale colour did not translate over to the darkness of her skin, otherwise she might've avoided this horrible, horrible fate xD

Generally speaking, I think you've done a good job! The colour scheme is what I really like about this picture :3 I might've said this before, but I am so used to my "dark and gloomy" colour scheme that something as bright and joyous as this always makes me smile a little on the inside ^^ I should honestly try and colour my own works a little more brightly ;_;
There's a lot of good stuff going on here, but what really drew my attention would be the lovely amount of textures on the background, such as the clouds and the azure sea. I've probably cursed my own inability to draw proper textures on stuff so doubly so am I amazed just how vivid the textures are that you've managed to implement. The water has that opaque feel to it and honestly with the smooth transitions from one hue to another, has that sort-of liquid yet form-fitting quality to it that one would expect from such a huge mass of water. A puddle of water and a body of sea have differences in their texture and I think you've managed to hit that difference spot on. The white sea lines might be a bit unnecessary but then againb, if you just made them a little smaller, I think they might actually work pretty well there! The clouds look damn good as well > Like, honestly, they have a really lifelike quality to them. I don't know how you did that, but I've never managed to make clouds look that good. With a soft blue shading added underneath them, you'd be set for life as far as clouds are concerned!
As for the characters, I'm impressed that you managed to get Ashley's outfit as spot on as you did, despite the fact that I've rarely used said outfit in my own drawings. I never actually thought about how summer-y that outfit was, apart from the waistplate/corset -hybrid. I'd like to think you did that on purpose, because considering how warm and bright Ashley's colour scheme is, it fits thematically really well! And Scylla's her usual self, lacking any common sense whatsoever xD And is it just me, or have her ear-floppy-thingamagics gotten bigger I do love the little flow you've gotten going for her lineart, it has a lovely feel to it, I admit. And next time I draw Scylla, I gotta remember that she has a serious sixpack on her ._. I always forget ^^'
As for the colouring, you've done a good work here, there's a nice combination of stronger and softer shadows and especially the textures all around make the picture come alive on a whole another level. And boy oh boy are Ashley's eyes just fabulous <3 What I'd like to point out, however, would be the cloth parts of Ashley's outfit. Under lighting conditions like that, it's perfectly reasonable that metal parts and skin would glisten in that way, what with the hard light spots and everything, but cloth doesn't really reflect light that strongly. Other than that, I have no further nitpickings about this ^^
All in all, damn good work! I should learn from you and widen my colour repertoire to match the level of warmth and joy that you seem to have in your paintings!
