Advice on character design from Valve

A design guide for character art in Valve’s popular game “DOTA 2” is available for free on their website.
The guide goes through some best practices for creating characters from their game, but the advice can be applied to character design anywhere. Some topics touched on in the guide include color choice, silhouettes, gradients and saturation.

Aspiring character designers should take a look at this short 18-page PDF document, and it’s really interesting for those not directly interested in character design too.
