Most months, I enjoy taking part in the Character Design Challenge on Facebook: They provide a theme and artists do their best to create a character design to match. It's great practice and I've produced a number of terrific pieces through my participation. Here are some of them.
'Freya Cirruström,' aviator / pilot
SpacePirate Flabjak.
Chef Demetrius Gumbo
Mukamuk (the caveman) and Woolly.
Crimson Viper, from Street Fighter, reimagined as a 1980s science fiction animated kids' show set in the distant future. Presumable, CV would go on secret spy missions and having wacky adventures with her friends Zangief and Juri.
SalesDemon
Glacelle, an ice cream woman.
Ninja cat Maru.
