The Indie Mixer is hosting a Game Environment Art Challenge wich you can check out right here.
The Mix’s Game Art Challenge theme is Original Spin, it is meant to challenge artists to take something from their past and put their own spin on it, make it interesting. We want them to exaggerate the past and draw us into a new world that we’ve never seen before.
To enter, artists need to create a concept scene based off of their favorite memory or place, something that has a special meaning to them. Everything created must be original and created during the challenge.
There are two categories - Concept (which ends on the 14th), and 3D (which ends June 2nd). Again, check out the official site for all the rules and such.
