Are there any tips for the program you're using you wouldn't have considered when you first started using it?

When i first started uploading i would use up to 50 layers for shading-lighting in SAI but now it's more around 5-10. It's hard to manage large amounts of layers so i recommend keeping them at a minimum. Also the "Recover Work" option in SAI 2 is an absolute blessing.

I also use Design Doll for my 3D references and only just discovered that you can save your hand and feet poses into a library :p
