Here's another commission piece I've inked over Arthur Adams' pencils. Skrulls! Here's how it looks before I did any work on it. Some of the areas were already filled in with Black. Arthur drew this about four years ago and when I told him I was inking it, he remembered he partially inked it. Great memory!
The person who commission me wanted the extra two Skrulls in the back left, which was drawn in a really light blue pencil. I could hardly see it in the original when I was inking it. I followed what I could see and referenced the line work from the other two Skrulls on the right. Here's how it looks when I was finished. I think that's supposed to be Kitty Pryde as a Skrull.
