Can someone pls tell me how I get a head texture??

Go to torishop > textures > head texture and buy it for 20.000 tc.

After that you can make your own head or pay someone to make you a head and upload it to your head texture.

after u buy the head texture(as pawned explained how to get one)go to torishop>textures>and then click activate>then select your head map(if you dont have one make one using ms paint or something)and then upload. and make sure your head map is 128x128
