Study Set 1 - Eyes

After drawing the regular eyes, I decided to draw the anime eyes off of them. To maybe help me out a bit with eyes in general. I think it helped a bit. I do realize that the 3rd and 4th anime eye's are too small. besides that i thought they were decent. I will probably fix them later though.

Note 1: Study set 1 is of human heads: eyes, ears, lips, noses, etc...

Medium: Pencil (darkened in Photoshop after scanning)

Note 2: I've never had a real art drawing class outside of middle school so i'm not real use to doing this kinda stuff. All of my art classes have been digital since highschool. So any real, serious critiques are cool. I probably need all the help i can get. Random comments and praises are welcome as well of course! ^_^ I could always use that too!
