I think you should enter it in the joint not here... but it's cool!!!

Thanks for your advice, I will try that on my next peice =D

Try coloring the black lines inside an object to a darker shade of the objects color. Makes it look a bit less flat in my opinion. You could scrap all the black in the piece and just make every edge colored.

But i like the lineart and all, nice. :)

You could use more contrast to make the shading look better.
