I have to find what a drumlin is (sounds like a hobbit), but I don't think so; these are just low rolling hills in the South of Holland (Limburg), with an occasional steep bit. No glacial stuff here, the ice didn't get that far.
I know about the trees, Oshyan, they worry me, because this needs to be rendered rather large. I might have to build a higher poly one. Can be done, because this one is only 10Mb, and I have plenty of 'space' for more veggies, memory wise.
