Alex Gaskarth

This is great. Very nice. You seem to have a good sense of different values. And the proportions are really great. I could see the likeness instantly. Hm, my only thing is, it seems you may over blend a bit. I get a little lost in the drawing, with all the different shadows and tones mooshing together. That's good to an extant, but I feel some parts of the drawing could stand out more, or could use some texture. The hair or clothes for example are a good place to put texture. The hair could have more strategically places lines, more detail. And the eyes could stand out more placing more attention and definition on the irises by maybe using a darker pencil, or just adding more detail in general?
And the lips, could have used a little more time spent on them as well. They get a little lost in the face.
But anyway,this is my view, I have no idea what exactly you were going for in this portrait, except to draw Alex. lol. But I sincerely do like this, it's very nice. You captured the emotion/expression in his eyes perfectly.
