I've been meaning to use this scan for a while and I thought it would be perfect for this challenge ^^ As you can see, I had a good bit of scan 'healing' to do to remove that nasty line and text, but I think it worked out well enough in the end. After that I edited the colours, sharpness, and used the burn/dodge tool a little on Eren to add some contrast.

I hope this fits the challenge ^^ thanks for viewing!
