Hi, I thought it might be useful to have a list of 2D tutorials here.
1: painting nose, lips, hair, eye
2: General (photoshop)
3: Many Gimp tuts and brushes at the bottom
4: Clouds-non specific
5: Clouds, weathered metal, fur, planets, mountains.(photoshop)
6: Hair and fur (photoshop)
7: Planets (gimp)
8: Links to Photshop tut, Drawing/Painting tuts, Matte painting tuts
9: Links to loads of Gimp tuts
10: How to make tilable textures (Gimp)
That’s it for now I hope you find some of them useful, you can add to the list if you want to.
