Here are some of mine:
Alliance Crest Embroidery:

My first ever attempt at embroidering anything, and I'm very pleased with the result. Mostly the product of blind guesswork.
Horde Crest Keychain:

A gift for a friend, plastic charms painted with acrylic and sealed.
Hearthstone Choker:

Plastic hearthstone charm painted with acrylic and sewn onto a blue calico choker. I love this choker, it's so comfy. heart
Draenei Mage:

This is...mediocre at best. Just a low-quality pencil-crayon doodle stuck on a screenshot. But it's WoW-inspired art, so I included it.
Draenei Paint Experiment:

I don't have much talent for digital art. This was essentially an experiment out of boredom. I spent some time messing around in paint yesterday, with this as the result. It was alright.
Night Elf:

This is one of my favourite pieces ever. It's totally beautiful in real life. Sadly, scanning it totally washed out the pencil crayon colours.
Alliance Crest Keychain:

This is my personal keychain. Made of the same materials as the horde one, and I love it dearly.
Skirt Sketch:

The initial sketch for a skirt I plan on making, one of these days. The alliance border print will all be embroidered.
So I'm sure you can all figure out which faction I play. =P
I'd love to hear opinions, and critiques. I do take commissions for crafts, if anyone's interested.
And by all means, post YOUR art! I love looking at other people's WoW art/crafts.
