You might want to work on the weapons a bit, they seem a bit "bulky" and whatever is the block beneath the ice and next to the wood could probably use a re-texture. Overall, though, it looks alright, I can't say for certain because it's been quite some time since I watched the cartoon.

So Das,

I see that you have rainbow dash as your avatar.

Nice pic man

you have 32x32 pixels USE THEM most of your textures have less detail then 16x16 textures
dont recolour stuff like you did with the mobs its lazy and looks ugly
and at last: avoid flat colouring
you have billions of colours at your disposal USE THEM even if you go for a flat/simple/comic style
