I feel I have a decent amount of eperiance in furry, not that I don't want to learn more tricks and tips. Stars are something I have little to no experiance in completely!

Personally... I picked Starfields and Planets. I visit JPL's site at least once a week, and HST once a month, but my starfields still look like runny paint with non-star-looking white dots.

In my case, I'd like to know how to do furry anatomy. I want to do more anthro art.

Chose "Digital Coloring" on account I'm not too worried about other aspects. I'm still learning (occasionally) how to do ditital coloring. So far, all I've got down is fill, burn for shading, and a special blur to smooth the shading.
