Cool terminators! I have a bunch of RT termies but never painted a single one of them. I did paint up the ten plastic terminators from Space Hulk 2nd edition though, but those are not as nice.
The Dark Elf army looks good, I wouldn't bother repainting them unless you ran out of unpainted old lead 8)
Are those Chronopia elves in the back with the spears/halberds?
The ogres look rather nice too, I think you should finish them!
