He and the bike seem to be good color and sharpness, and I like that you caught an expression, the way his face (and the tongue sticking out a little!) show how intent he seems on what he's doing.
I would suggest you think about backgrounds, and think about your vantage points and how that changes the perspective and how the background changes. Think about if you want all those signs and fire hydrant etc. or not, maybe frame differently to not have so much of that since it doesn't really add to the picture.
Think about the other person, either she should be in the frame and part of the picture instead of blurry in the distance, or keep her out of the frame (for this shot). If you want her in a picture, try to get her when he's closer to her and use a small enough aperture to get them both in focus.
