I love that someone was making Young Avengers content! I adore them (and love that all but Teddy and David have shown up in the MCU), and I can not begin to tell you how much Kate Bishop is my girl, she was one of the first characters I ever had a legit cosplay for and one that I'm know for tbh. Just a hint, because I know that suit so well, the hip cutouts go a bit too high, they're supposed to center right on her hips. and not only is there the shoulder cutout on her left arm (that could be bigger and farther down her arm), the right arm doesn't have a sleeve at all. Nice details with the cuff at the bottom of the pants though.
I will also say, not every young character in Avengers media is a Young Avenger (I keep seeing that though), It's a specific team. Not every young Avenger is a Young Avenger, if that makes sense. Characters like Miles and Kamala were never Young Avengers, they ended up directly on the main avengers team.
It's all well done though, keep working and you'll keep improving!
