Can one use alter appearance to change the color of ones scales(give them a metallic sheen), change the color of ones eyes, and/or change spinal ridges. Basically what are the limitations?
I don't think there's any inherent limitations in the spell as to your questions...keep in mind:
1) You cannot impersonate a particular person
2) Whatever changes occur, the bonus/penalty are fixed
If you want to get creative and say the scales are given a metallic sheen as a positive effect, I don't think there's anything suggesting you can't do that. If you say the scales are now Rainbow Colored with Pink Polka-Dots, that's probably not within the spell's effect.
Overall you're either creating a more 'positive' or 'negative' appearance, and things like spinal ridge appearance, scale color, eye color/shape can all work towards either of those effects.
