What would you like to see me do better? (Pixiv Fanbox)

Hey guys!

This is kinda a bit outside my normal posts, but I think this is the best place to ask since you're all on the front of liking my stuff :D

I always want to improve, and I feel like today is a good day to take criticism (so please dont hold back) :D

So basically, what do you guys think is my weakest point in art? Or what should I focus on (in your opinion) to make my art better/more attractive/hotter etc? Obviously you all have biases, some of you like bubbles (you know who you are :D), some just like to see drowned girls. But if you look more objectively at my comics, what areas do you think are the weakest? Or what is really good, but would be even better if I improved it in my style?

Personally I feel like I'm super bad at rendering, especially backgrounds. Without context now and then, I think none would know that the entirity of the Kurumi sidestory happens in a tub ^^ So thank you guys for your great imagination, saving me the work of drawing a detailed tub over and over :D
