After looking through your gallery I can give you some advice. You could try to improve on body proportions and try to center your drawings. some are way/little off to the sides.

proportions & anatomy i'd say.

proportion/anatomy practice. maybe mute your colors just a bit, try not to use so much contrast, especially with the backgrounds. your eye shapes and hairstyles tend to be similar, so maybe work on varying those.

but most of all experiment !! you'll be better nd better in no time bb
