It means everything, really! Shading is something I've been trying to get down for a really long time, so I secretly pride myself in the mushroom teardrops pic :p
That is a damn good link, I really appreciate it. My struggle is manipulating the shading so that the fingers/arms are coming toward the viewer in a 3d perspective. Gosh what a poor way to describe that. I hope you understand. I'll be sure to study the resources you've been so generous to give me and share what I've learned through more drawings. Thank you!
