I'm not a beginner in the toribash game but I am a beginner in GIMP 2. I'm not sure it it's okay to post this here but I'm 65% sure that It's allowed. I just want people to post here some tips on making heads. Thanks toribashers!

Hey, there are some tutorials around the forums, for example:
Fate's basic emo head
Pate5's texturing guide
NinjaTori's headphones tutorial
Chris' hair tutorial
Pate5's robotic textures
Eddy's bumpmap tutorial
Doxxy's shading tutorial
Ezeth's human drawing tutorial

I guess these are enough for you to try out and improve your skills. You can also PM me, I've used GIMP 2 for more than a year.

Thanks pal.
If anyone else has some tips, feel free to post.
