I agree the terrain looks to flat in some areas(BF2's Geonosis is about as much flatness as I can take). My diagnosis(just what I'd like to see, it is your map)
Too flat, add debris like crashed ships, rocks, or raise/lower the terrain in some places.
Too big, bigger is almost always never better. I don't like walking on foot for half the battle. Either make the map smaller or add big things like coreships to take up some space.
Too boring, I don't mean to sound rude but you need something to set this amp apart from the other million geonosises out there. Campaign could be just what you need(I love the CIS

I almost never play as the clones, airgo B-1Burt)it doesn't have to complex just fun and interesting. Add some crashing capitol ships,(I've never seen this in any map, let alone geonosis)use that LAAT dropping off the AT-TE animation, or make a CP inside an
Acclamator flying way up in the sky with ships you could fly down to the surface(of course the CIS would be able to destroy this

)
Download both the Sriaden and Raxus Prime, compare how you could use some of these techniques to make your map better. Raxus captures the Raxus from Star Wars: The Clone Wars
but is too big, Sriaden is flat mostly but it doesn't feel flat because of terrain variation.
This map could be awesome if you want it to, keep up the good work.
Edit: Needed some commas.
