A Peek Behind the Lines

So here's a bunch of stuff I did recently, but with a twist! It's a peek behind all the line art, so you can see what I actually did. All the finished pieces are on my deviantART page, and there are two versions for you to check out here. The first is my colors, with all the lines completely removed. The second is my colors, with the parts of the lines that I colored over to help the flow of the final piece (this process is called color holds). First up is a commission I recently finished for Justin:

No Lines:
Color Holds added:

Next up we have a piece by Al Rio that I colored, first with No Lines:
And now with the Color Holds added:
Next up is the result of a brutal battle between Batgirl and Catwoman, first with No Lines:
and next with the Color Holds added:
And Last we have a quick sketch that I colored as a warm up, of Poison Ivy in her outfit from the new Batman: Arkham Asylum game. There were no color holds on this piece, so here's the version with no lines. You can see how rough it is, especially compared to the others.
