Yes, it does look a tad bit feminine, honest opinion, but no need to worry as I think some men have even more prominent man boobs so its not something very unusual.
Also yours seem like a size A and do not look bad (unlike most men) and it seems feminine mainly because your undersides (if you can understand what I mean) seem bulky or fleshy or maybe its the picture angle, losing some weight or gaining some muscle mass (or looking more muscular) by strength or weight training may help if you want to get rid of it but if you don't, then just enjoy it
