I have a better resolution on my pixiv
www.pixiv.net/member_illust.ph… :3
It's not my full resolution because I don't usually give my high resolution picture to anyone else. I've had of some troubles in the past :/
But I'm very happy you like my picture that much that you want to make a poster
if the resolution is still to small let me know I'll think about giving you a high resolution
and if you want to support me you can check my redbubble
