I´m so mega happy that my advice was helpful, you just made my day right now ;u;
LadySmaug is my name now, i use it on almost every platform so why not use it on colors 3D too? (actually LadySmaug was a bullying name people used to call me ages ago, I´m now proudly using it myself while planning on revenge...*evil laughing*)
If you like citique, you can have it: The colors you used in this piece are very pretty an fit together very well. Also the character design is very very cool and unique, i espeacially like those mushrooms! Oh and leg are pure evil. try using a reference sheet for them or look at human skeletons on google images. that might help :)
the only thing that mocks me a little, is how you made the grass because its a little sketchy compared to the rest of the image. You could make the grass look more comic like, to fit your style or even give it more depth by adding lighter and darker grass blades. Give the grass as much love as you give to your characters :3

If you are bored and have some time(like two hours or so XD)
check out this tutorial from my idol artist aaron blaise on youtube on..."how to draw grass". yes. A two hour tutorial on how to draw grass actually exists XD
its called:" Aaron Blaise Live Stream - Grass / Enviroment Demo "
If you want to improve, i strongly reccomend this guy to you. :D
