Well think about a family portrait. Would they all be situated behind a wall with only the top of their heads showing? Probably not but I'm sure stranger has happened.
Portraiture is pretty straightforward by definition. Bending a little is always fine but the more you bend the better the photo has to be to compensate. IMHO.
This is my second go around =) - so cute!!! Not really a portrait, but still should do very well! I love your idea! Your kitty's colors also look very "camaflouge" so this picture really fits him/her. Great idea!
How adorable! I love calico kitties and this one is no exception though I would like to see more of it! :) Cute idea, nice candid but the tree in the middle is very distracting, maybe if you cropped more on the right, making the tree the right edge, taking the kitty just off center but with my magic envelopes, it looks very nice. Had at a 5 but am going to bump to a 6 for cuteness and nice capture!
I really hope this ribbons! I've only said that to three other shots ahaha. This is a wonderful photo! Portraits should evoke the personality. This gets an A++, er...a ten :) Good luck in the challenge!
