Ursula Vernon (an extremely talented and witty artist, check out her stuff. Seriously. She's a pro.) Was holding perhaps the second or third Art Challenge in her Art Challenge Live Journal community. I decided to try my hand.
The topic was something along the lines of 'Fake Magic: The Gathering Cards'. And one of the proposed cards we could draw was, 'The Fortess of Wo'mbat. It's a bad place. Evil people live here.' I'd link you to the original post but, seriously, it's an active community and happened months ago and it's 7 in the morning and I haven't slept yet, so I'm too tired to look. ^^;
Uuhm.. Yes. So it's an evil fortress done entirely in Painter 7. I hope you like it. And check out those links above! You won't be disappointed.
