I will critique the first photo I see.
I think the clarity is too low. It's okay to lower clarity for closeups, but in this case, the hair is so blurred it looks like butter. Try to selectively lower clarity for skin, or increase clarity for hair. In fact, the clearest part of this photo is her black sleeve, and that draws attention to the sleeve. But I'm assuming we should be looking at her face, not her sleeve.
I like the even lighting and the good composition. Cosplayer is attractive too.
