Actually, I think the solution is even more basic that what everyone is discussing, regarding the looks.

Original Dark Curse, everyone suffered a memory wipe except Regina. As part of the curse, Regina made sure everyone looked "Normal", which is why Jiminy was returned to human form and Gold was descaled.

Second dark curse was really JUST a means of transport from FTL to SB. Zelena added the short term memory wipe. Everyone that was originally part of SB reverted to their SB persona. The new people, such as Robin and his Men, maintained their appearance. same with the third curse and the Camelot people.

Zelena looked normal because she glamored herself to look normal. at first she wanted to blend in, and obviously could not do so with Green skin.

Emma did not feel the need to hide who she was, and so kept her DO appearance to make the point that she WAS the DO. The only thing she did was to fix Killian so that he looked normal, since she was the one in control of the memory wipe. And similar reasoning would apply to Nimue, plus the fact that Nimue's appearance in SB was when she came straight from the UW.
