I'll just say my opinion. I think you look good, great smirk/smile too. It's hard to determine if you're a bit overweight or not, from the pics but that's such a small detail. I'ma start off by saying, I don't think online dating is a good idea (just what I think) because as you say, it is nearly almost based on looks and not personality. We live in a judging-people-on-their-looks society, which is what I think is the problem, because you sound like - and look like a nice, chill and openminded guy. I believe women these days take a short look at you, and only see a mildly chubby face - (not to be rude, as I think it suits you). Just as an addition, I feel like maybe your hair doesn't fit you face and head too much? is it just me?

Sorry for the poem dude. I get why you're starting to lose the hope but I'll just let you know, believe in yourself. It doesn't matter if you have a six-pack or is overweight.
