The background image wasn't drawn by this artist. Not surprising since this artist seems to traces other people's work. Couldn't find a source image for the character but I found the bg pretty quickly.

Linking to TinEye searches like that doesn't work since they expire after some time.
The background is from the game Smile Cubic!, it can be found on E-Hentai.
