My Life in (no longer) Paris - Photos from my two months in Paris and beyond - Brendan contemplating

Another shot from the studio session. Critique from the review class: needed a little fill on the top right so his hair doesn't sink into the black background. I agree - tougher to do with one light source but I could have worked with the reflector a little better. My instructor also wasn't keen on my off balance composition, cropping part of his arms, but I really like the composition. So we can agree to differ! There's no real wrong or right in art. Any other opinions on the composition?
