based on your current avatar i assumed your eyes are both the same size, and at the same level..
the hair looked a bit weird too, like it was drawn and then rotated clockwise a bit
but the biggest item (at least for me) is that its kind of messy, like your current avvy.
there were random highlights and shading spots, which makes you look like crumpled paper more then human flesh (again. i assume you're human)
i most likely killed any resemblance to you though.. maybe post a reference so we can critique on likeness?
for now, keep going, you'll get there.
Oh my god! I love your edit. Can I use that pallete, I'll admit I don't really like my current one.. And yeah, looking at it agian, there are many errors, which I will fix, thanks for the comments
Oh, and for reference, I doubt this looks anyhting like me, I am probably starting over, nad trying to get the likeness down..but I suppose I can post it...
yup, not much likeness..ugh I have alot of work to do
