Funky directional lighting! =)
Hmm. I find the centre bright line a lil distracting, is it from the built-in flash? Mebbe you'd like to use a cable instead, so the flash won't have to fire. Alternatively, use HSS mode (1/160 with AS on) and the built-in flash won't contribute to the exposure.
The right side seems a lil dark, maybe you'd like to add a reflector (small one) to fill in the shadow a little bit?
