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!
Well, to be honest the illustration on the top was my second attempt to this drawing. The first one appeared to be "flat" so I redraw it learning from my previous mistakes In general I painted with very diluted watercolors first. Then I used a pen with brown ink to emphasize mountains and stone textures and for drawing trees.
