Meh, since you used scanlines on the chainmail for the neck, you'll have to use it everywhere else there's chainmail.
If there's too much scanlines on it, it'll definitely look weird. Maybe experiment with the "Apply Canvas" filter.
I know you have Photoshop but a lot of filters are in both GIMP and Ps, so I don't know. It's really neat.
Other than that, you're doing great so far.
