M.E.C.H.: The Reboot

Experimental project, tried to combine a freehand sketch in my sketchbook with a 3D rendered environment.
To combine these 2 I merged them together in Photoshop and started to paint on top.

The natural brushes are not created myself, but found them on Deviantart, to make sure I make a proper credit, here ya go:
