I'm really bad at visualizing, even when I do the whole "draw your light source" stuff ^^; my brain does not seem to understand how curves and the like work. Also I forgot that Dedenne was a potato, oops 8D
And yeah, that's kinda the fault of the design, Dedenne looks like a potato with ears ...
I also don't really know how to do shading, I guess it comes just naturally to me because I have good visual thinking (on the flipside: I am dyslexic :I ).
But yeah, I guess reference pictures help? I don't know :I
