I use Paint Tool SAI. Also this is the first picture and its very old. I bought a new notebook and I can work with it a lot better.... I learnd a lot the last week about practicing lineart and shaping. Wait a minute I upload four you a picture of one of my newest creations.
I saw you gave a warning with the yellow crystal thing, but he obviously ignored it. If people ignore a warning, ban them for 1 or 2 weeks depending on how big the incident is. Also, don't give more than 2 warnings. Just a tip ;)
