Thanks for the feedback, everyone!
I agree that the crop is too close on the left, but I didn't notice until I'd put everything away, and I was too lazy to get it all back out again and re-shoot.
As far as the angle and arrangement, there were reasons I chose them, but that doesn't automatically mean it works, of course. I chose a tight crop that didn't show the whole shoe because to a daughter, a father is often perceived as larger-than-life, so I thought by not quite showing the whole shoe that would kind of lend itself to that concept. I also accentuated the scuff marks and wear on the big shoe to indicate this was someone who works hard. So ultimately I was trying to tell a story - hard-working father, and the daughter who adores him but doesn't necessarily see everything that he does for her at the same time.
The only reason I didn't shoot it from floor-level was because I was trying to use the carpet as the background, so that's not really an excuse. Just more laziness. :meh:
I appreciate the input a lot though - I may attempt a re-shoot this evening, with a different location, slightly harsher lighting (for drama), and try out some different angles.
