This is a really interesting image, and it's great that you invested this time; I just encourage you now to push it further and further - and also, consider developing your facial characteristics via profile/turnaround images (not sure i know what your nose looks like, for instance). More, more, more! :-)
Saw you painting this at Uni today, it's very interesting. The eyes are great, one thing I would say is watch your use of the clone tool, you can spot it on the upper nose between eyes for instance.
Wait, I just realised the difference in the pictures, you copied/ rotated the eyes, making that bit cloned. Just paint it out really.
Jon's right; Photoshop - with all its tricks and 'helpful tools' - can encourage a kind of handicap; it withers what would normally come naturally - i.e. the need to paint (as opposed to clone, for example). The one thing that those life drawing classes should impress upon you is the sheer delight and satisfaction of hand-crafted mark or gestural line. Don't subordinate your skills (and skills-to-be) to Photoshop gizmos; just paint with confidence and with curiosity!
Sorry for the confusion between the two images XD I didnt have time to caption these images because i had to post them and run for my bus... but i did angle the eyes in the second image and i did use the clone tool as "sortcut" just to get a rough idea what it would look like. However, i dont like the eyes slanted i think it makes me oriental looking and less like me so that experiment is a no! no! in my opinion.
I agree actually. I prefer the first image.
