Overall, looks good. I notice you have your wrists cocked back, that doesn't hurt your wrists at all? It's a somewhat unconventional technique, but if it works for you then I won't try to stop you.
It looks like you don't use much leg drive, if at all. There are some good bencher who don't use leg drive at all, but it's something worth experimenting with. There is a recent post on Boris Sheiko's facebook page that you should check out.
Other than that, I would advise having someone spot you (someone competent, that is) or benching in a power rack. Apparently there are a few people who die every year from getting stuck under a bar, don't let yourself be one of them.
