Little Green Man Who'd Rather not be Here

Grumpy alien scientist, who'd rather stay in his bed, but will show you his laboratory anyway.
This was one of the first artwork I exported from Krita, the main problem I faced then was making the colors show up correctly in .png format. I don't remember the details, but the problem was I wasn't using 8-bit integer channel + sRGB built-in color profile. I know now how to export png files from Krita, like a champ!
