I liked the maps but i think you could easily reach a bigger audience, too.
The quakeworld community is dying for new good dm maps, and all your help would be needed.
Even now when I'm looking at terra6, it's got some excellent places that would rule in a fast-pace qwdm 4 on 4 match. It's also about the right size. Alas, it lacks dm entities and some more connectivity might not hurt. (A bit too much dead ends and long corridors?) But first try could be with just some dm entities! Putting spawns, weapons and ammo there. Remember, a lot of people like many of the original id episode maps, that weren't really designed with dm in mind but happen to work in dm anyway!
Dm mapping can't be super-hard, and you can always refine the maps or in the end do just some entity fine-tuning. (with dm I usually mean 4on4 matches like at www.nqr.nu)
There was a a custom map tournament, and from the maps made for it, cmt3 and cmt4 are most popular now, so you can run around a bit and check on "how its done". :)
Of course, dm2, dm3 and e1m2 are "the big three", unsurpassable classics, and it's worth looking them a lot too.
Really, making dm maps could be rewarding! If there's a better place for this discussion, inform me :)
