Good stuff, all.
I'm gonna throw down now.
Working on some backgrounds but I'm really, really lazy when it comes to them.
Some quick colors:
Backgrounds can be very time consuming but I think you did a nice job.
I do think though, that your main figure needs to be a little shorter compared to it.
If his head was at around where his shoulder is now, I think they might match up better.
I was messing around for a while with streetback ground for my piece but I just couldn't get something I thought worked.
I really struggle on backgrounds.
So I took the easy way out.
Another minor thing I think would really make a big difference is the manhole cover in the foreground.
Spending longer on it because it's at the same level as your character would really add to things. I'd think that you would be better off with out that detail if you wasn't going to fit the other objects in that area.
