as i've said before, your art is so so pretty aaaaaaa
if you really want criticism, maybe try some different shading teqniques?
i find that colored shading typically works a lot better than just black shading. so colors like brown, maybe blue-ish or purple-ish, or you could just get a darker and more saturated color of whatever color you're shading, which is what i've been doing recently. i think that the result is pretty nice!
