I Like! You're a real good drawer! Keep drawing, you're way better than me :p I love how you added detail to the shirt, it really puts the final touch to the picture.
The hardest part of living is just taking breaths to stay.
So, I typed a review up and it somehow disappeared. Sad day.
Anyways, I think this is nice. You have great soft lines and the shading in the clothes is superb. However, I do have two things that I think you could really work on.
The brow and eyes are both... iffy. The guy's head in general is really oddly shaped, but the brow sticks out at a weird shape, which shouldn't be too hard to fix. The eyes are awkward. I like that for the majority of this you kept it manga-ish, but realistic at the same time. I think that you could probably work on the eyes, make them a bit bigger if you want for the anime thing, but try to make them a bit more detailed at the same time. Allow some room for a detailed iris, maybe a reflection, and I think it would look much nicer.
The second thing I had a problem with was the collar. I realize that it's a sweatshirt thing, but right now it kind of looks like a furry animal that is slowly creeping down his body to devour him whole. I think that if you were to flatten it out a bit, make it more of an angle towards his shoulders rather than an arc, it would really help.
I like this drawing! It's better than what I usually draw. Persephoneia did a good job at pointing out the slight mistakes, but I really like your drawing! Keep up the good work!
