Oh yeah, this one is cool! Especially the white wrist thingys I love for no particular reason 
Maybe the hair is a bit undefined - I can't imagine how that would look if you ever saw it translated to 3D, not because of lack of detail but... I feel like the volumes and perspective isn't on point yet. And the red bits, even though they work great on here as illustration, I'm also not 100% sure what they are. Is it leaves? It would be fitting I think...
Personally, from a design point of view, I feel like you have too much colors going on. They work well, sure, but I'd try to kick one out (the blue on the chest). If you look at the shoes, it works great. Lantern, great. But the torso and head area are a bit too crowded with stuff and colors so it makes it harder to read. (leave out the hanger too, come to think of it, opens up the chest and lets the eyes rest for a second) Less is more! If you give it to a 3D artist, they should add in finer details, but the design will work better simple and straightforward. Imo, that is 
Oh another something small but also from a design point of view; the shapes/patterns you use on the orange-brown chest piece don't match the ones on the hip piece. I'd say choose one and stick with it; either curly wurlies or angular scifi shapes. (Or organic scifi shapes like in the wrist thingys which I love so much and remind me of Skydoll)
Cool work, nevertheless!!!
