i think you should re-name this sub vs. Reptile cuz to be honest he's looking more like reptile right now...maybe it's the eyes. I know it's the same as sub's except flipped horizontally, but from this angle it just looks reptilian...maybe make another fake where you finish the look and completely turn it into reptile by changing the skin color or something? also in the original pic, you could see a dojo on sub's side and a gotham skyline on batman's side, so maybe you should add something more to the background. since it's noob, maybe put some netherrealm mountains or whatever. also, this may be something VERY picky and subtle, but I just think for any kind of versus pic like this, if the background is a cloudy sky or something similar, there should be a bolt of lightning cutting through the air. It just seems to add that tiny little touch to an "epic battle".
