well, as i started with all that stuff some days ago, it will last a looooong time till im so good to maky my own avatar. But i have good ideas - if im really used to that i think i can make a good avatar
If you think you aren't good enough to make a good avatar, then you can always take a screenshot of one of your wc3 resources, like skins, models or maps. Then it's still sorta yuor own work.
To make a screenie avatar cooler, is to make an animated .gif out of it. You can also change the angle of the camera, so it looks extra cool, so screenie avatars can be cool, and I personaly think that that's much better than a stolen avatar from the internet.
I like Crazynutter's and Rui's avatars. But Vexorian's old is still my favourite. And olofmoleman you should change back to your parasaurolopus avatar. It was sooo cute!
