DTIYS of the week

This is Kat, a character from @kyarix_ on instagram. I'm new here in Pixiv and I'm still learning how to use, this is like a social network for drawings? Hehe idk but I loved and maybe I'm addicted. The drawn: What is your opinion about it? I need constructive criticism to improve <3 (I don't know, I didn't like the eyes, to me it looked like two cockroaches lol)
