New base ideas for the eldar

I've been wracking my brain for ways to easily differentiate between the nine 5 man squads I'll be running with my Dark Eldar list.  I was browsing some of Jim Wappels minis when I noticed a basing style he does a lot of the time on his 40k minis that basically  involves creating some sort tiled floorwork.  He often paints his minis with bases that appear like they've been ripped directly from a temple or some other really interesting groundwork.

So, here we go, my first two attempts at this style of basing.

What do ya think?

Possible design for troop venoms?

So I saw a neat little tutorial on doing starry backgrounds with an airbrush and whipped this thing out in about 5 minutes.  Obviously it's very rough around the edges, but what do ya'll think about it if I can refine it a bit?
