Shading tutorial (Paint Tool SAI)

Mah first digital tutorial!

Well was planning to make a little tutorial for my friend that had some problems with shading...but I've put more work in it than expected so here it is!

I don't use Paint Tool SAI, so Im sure that there may be other ways to shade, but it works just fine!

I Hope it can help someone
