I know how Ady wants the things remain hidden and not all revealing in dagobah.

I like his approach.

Still i enhance slightly the matte so it not look like a painted wall. + a more bright light so the eye locate more easy the fallen X wing

Plus i made dagobah planet more green (from deleted scene from ROTS), so is not looking like Hoth.

We see an indication of green after luke departs from dagobah and going to cloud city, so why not.

Last when the X-wing enters the atmosphere of dagobah i slight open the fog to have some more depth. nothing fancy.(also taken from ROTS deleted scene).

Edit:

"Lastly, any thoughts on possibly making some of the animal life on Dagobah a bit more "alien"? Even if only by doing some subtle color differences or exaggerated features?"

Id love to see an alien egg from ALIEN movie as an easter egg!
