You are very cute! Like others have said prior, the eyebrow tinting is actually pretty good, but it wouldn't hurt to touch up a bit
I love KnB, and my brother is even planning an Aomine Daiki cosplay! However, I do have a few little notes. Like you said, Kuroko is very simple, and he as a person is not meant to stand out at all. Since you are doing a genderbend, I would stay true to that key characteristic. The false lashes are a bit much, I think (unless those are your real lashes, then OMIGOD I'M SO JEALOUS.) and maybe you should try something a bit more natural looking? I imagine Kuroko, female or otherwise, probably wouldn't wear much make-up, if any at all. Then again, it is cosplay, so if you don't wear any make-up you'll look washed out on camera. I would suggest using brown eyeliner rather than black, and using natural tints to bring out your eyes rather than using such a bold black. There are lots of tutorials online for natural looking make-up, so why not take a peek at those?
Hope I helped,
If you're ever in the West Coast, you and my brother should totally do a KnB photoshoot ^.^
