Where do you buy different color/type heads? I had some trouble in the shop (still newbie, not very good at navigating through shop).

You do not buy different colored heads. You buy the item called 'head texture' for 2,000 TC.

Once you buy the item, activate it, and then you are able to load an image onto the head. There are many tutorials on texture making if you are interested, just use the search button.

If you do not want to make the image you upload onto the head, you can buy one from another user, alot of users sell textures. It would be in the Art and Textures section.

Do you know how much the average (user sold) head costs?

can cost about, 1k-7k for a good head texture. this is from what I've seen in the forums, and heard in game.

Wow, then I have some work to do, I only have like 120 TC. But I have spent about 100-150 on blood, and other types of stuff.

Play tons of official games, and if your a decent artist enter some contests under "Design Events" or check for tournaments

yoiu can buy a head "TEXTURE" for 2k and make your own

Or you can use your /custom folder. It won't show up to other people, only you can see it.
