Valentine from Skullgirls~ If you haven't played Skullgirls yet then you guys are missing out, really! I love Valentine(and Filia is also cool too!) It's a really fun game and I felt like doing a quick Valentine drawing. Hopefully I'll do a better one next time...ORZ'
Oh gosh, I haven't drawn big boobies since I last drawn Morrigan asdfghjkl;'
You'll get there eventually, just keep doing what you're doing You should check up on Capcom's artbooks(UMvC3 is good), they help A LOT on anatomy! Or maybe find inspirations from looking at Skullgirls arts.
The hardcover is 100 bucks but the soft one is around 25-30. You don't have to buy the book honestly but just by looking at a couple of artworks helps a little. Here's a clip from MvC artbook [link] Hope that helpsヾ(´^`ヾ)))
