I found a great tutorial today on Only Pencil by artist Lisandro Pena on drawing a realistic eye. The human eye can be a very difficult thing for many beginners to draw. Lisandro explains in the tutorial the importance of studying the eye, or any object you want to draw for that matter, so that you really understand what it is you are drawing.

He provides the tools he uses as well as a step by step lesson with pictures. He has a lot of other great drawing tutorials on his website as well. This is definitely a great resource for drawing enthusiasts.
