I like it, but at the same time there are a few things I would change. Bear in mind this is just how I'd do it, as I do like this figure.
I might try a different set if arms, as those to me are just very POTF2-ish. I would try using more parts from existing newer Jedi figures. Really that's the only thing I might change, and maybe add just a bit of a wash or dry brush to bring out more details,
Fun to see a Bith Jedi though, and this is nice work.
