I've realized now that Yokaiden is out, I can stop being so secretive and start showing some behind-the-scenes stuff. I just finished doing some concept sketches for the cover of volume 2. They're far nicer than the sketches I did for volume 1.
When I do concept/layout sketches, they are 1) very small, and 2) very messy. The cover art sketches aren't so bad, because the guys at Del Rey have to be able to understand them.

My thumbnail sketches for my comic pages (used to plan the panel layouts and where the figures and speech bubbles go), however, are atrociously messy and only I can understand them. Fortunately, I'm the only one who has to look at them. Each one is roughly 1.25 x 1.75 inch in size.

Since I prefer to keep everything in my head, I'm bad at noting/scribbling things down onto paper. So when I have to do it, it's extremely vague because I can figure out the rest myself. I look at the thumbnails and go, "Oh right, the speech bubble is here and the figure is posed like this here", and that's good enough for me.
Bonus unedited scans of my thumbnail sketches for chapters 2 and 3:*

chapter 3 roughsHave fun following along!
Next entry, I should show how rough my pencils are before I ink them. My pencils are NEVER tight. Well...except when I have to do pencils for Bongo.
