You are pretty good. :)
I like your shading.
Can I give you a little advice? When I do faces I draw myself a vertical line through the middle - really lightly so it can be covered with shading. And a horizontal line between the top of the ears for the eyes. It helps me keep the alignment.
Well I used a ruler to fix proportions, but the ear kept looking wrong so when I changed it it just got out of hand. Thanks though =] This is my first portrait, and advice and comments are /always/ welcome.
I think for your first time it looks great.
I was not really talking about fixing this one.
I'm so used to working with burning iron; I don't fix stuff.
I meant in the future, so you don't have to worry about fixing anything. :)
