A while ago I was offered to do a test for a massive concept art contract. Unfortunately I didn't land the gig (due to some mis-communication from the potential employers), but it prompted me to work on my concept art skills.
So I did a couple of ImagineFX challenges with goal to keep them rough and do them quick. Although I still struggle a little with the quick part, I think I'm getting there with the roughness.
You can let me know what you think of them in the comments section...
