Here is what I have done so far, not much as I am trying to finish my course work as well
Second board for DBA games, this one is less deserty and more arable, not totally convinced as I used bits of off cut grass roll then sanded around it rather than usual sand and flock.
Looks ok really
Then I did some hills for it, going to do some small pennies of bushes and rocks to sit on the bigger bases to be scrubby ground
Also did some for the desert table
Totally flat DBA terrain is best to play on but I am prepared to have wobbly modles and add in some 3D to the table.
Next on the list is a camp as the first one is too medievaly to do for Seleucids etc
Should get it done in time for our local clubs DBA day, may even get some undercoat on my Romans and dont get me started on the BUA I have started.
Needless to say have become a little obsessed by DBA at the moment
