Here's your commission, sorry for the delay I've been sick. ;u;
I worked really hard on it, for literally hours, mostly bc of the animations and I noticed the icon ( original vers. ) was too big to be used as an icon for your group, but you can use it on your group page as additional decor!
I have it named as the 2nd one, but the first one is the right size for your group.
I do hope you like it, I did a jungle/oasis theme as you asked.
With rain and tiny splashes, fog, light shining through+little spots of light, the name of your group on the icon, dew drops on the leaves, a waterfall, etc.
Since I couldn't fit in your OC, I opted for adding a lotus flower in the water instead.
I do hope they're good enough and what you had in mind, I added tons of plants, including bushes, the flower, trees, vines, leaves, etc.
Here are both versions:
Have a wonderful day, thanks again for commissioning me and for being so patient.
