This silly thing took weeks--I think part of it was because the only actual drawing I did before scanning was Undyne herself--I wasn't sure exactly how to handle the background so I planned to just figure it out in Photoshop ... which not how I'm used to doing it, which lead to procrastination. I think I spent more time procrastinating than actually working on it.
I don't think this one is better than the first Undyne drawing I did, but it's good enough to work as a companion piece.
Also, in both drawings, Undyne ended up looking bustier than I intended--I think it's the strong highlights on the metal that makes them pop like that. The way the armor looks in the game makes me think that there's a suggestion of a female chest, but with only a slight "bump" to it (she's super thin under that armor after all). Okay, enough about Undyne's boobs x.x
