Sounds pretty normal, I think the coloring is shed related, and the yawning is pretty frequent, with Pickles. But thats just my . I'm no expert, not in the least. (Pickles is my first herp)
edit: WOW, dr del, that dent scares me. Glad it got resolved with the shed.
dents in eyecaps are hydration related. Boost the humidity and the dents will go away.
