Personally as a guy who by standard isn't "attractive" I don't look for "physical looks" so long as we connect then I feel there is a connection. But as a lot of others posted, men are all different so... What I like'll be different from the next guy. Sorry on the wordy response. :p
For me, mainly someone who is more on the intelligent side (At least knows what they are talking about when they speak) and nobody that's condescending or a bully. Now, looks should always be an added bonus in a guy's opinion (at least as far as I can tell), but if I had to judge looks I look more for blondes/redheads and on the slimmer side. Again though, looks don't matter as much as personality. :) good luck!
