Well, I guess it's just a matter of practice I'm much more used to make traditional drawings, so in my case it's easier to keep deadlines with these kind of works. From time to time I make also digital drawings, but it takes me more time.
That's true, and awesome that your able to produce such high quality work quickly! Whenever I look into game art or production there's loads more digital than traditional. I've always loved working traditional but lean more towards digital if there's a chance that large changes are required. Thanks so much for sharing!
