Hey so, I thought it'd be a good idea if we had a spot to share any nice tutorials/resources we might have found.

Also making this thread because I'd like to know if anyone knows a good resource for shading techniques with pens (Starting to prefer pens over pencils). I've tried to find some myself, but have been having difficulty. I typically in my sketchbook which is a paper-bag shade of brown, so I can't use empty space as highlights as easily. Main problem is that my hatching doesn't seem to work well for spheres.

I'll start off with this really cool pixel art tutorial. Also goes over some good concepts: http://www.pixeljoint.com/forum/foru....asp?TID=11299

Gonna throw some more in later. Would love to see what ref's, you folks use
