I went to school for Art. Several thousand dollars later, I'm still in debt from it- and I can't say I gained as much as I lost.
This game, for its price, teaches you the basics of many skills such as:
Crosshatching, layering, Highlights, use of different hardness' of pencils.
I really enjoyed this game as it leads you through visual tutorials, and then has you make your own piece of art. Yours will never be exactly the same as theirs, and yet I've been pleased with the result each time.
This is great for anyone interested in either refining their skills or learning from scratch. I really recommend it.
