In perfect defining focus except of the upper left corner that was too close to the lens - perhaps you could go for hyperfocus, Olga? The balance of the exposure was also a good one as it kept most important details except again of some overexposed regions (left part of face, left leg) that nonetheless fit well the "sunny" impression.
The composition in that angle does convey much spontanity and natural movement of the happening, and this is a good thing especially for arranged portraits, since many many times they try to look so spontaneous and they look only silly. I think that it only helped to not include the whole bike in the image - so it remained a good portrait too.
Only the face could have a bit more plasticity through shadows. It is already 3-D but a small correction toward less exposure could enhance that.
