Land generator for my game - please criticize

Miscellaneous Forums/General Discussion/Land generator for my game - please criticize

Finally, I have written some code for columns to hold up the
floaty chunks of land. Phew, 2 weeks later and 6 more pages
of code added to my project and I've got this to show:





Sure ain't much. Hope you guys like it!

I want to know how this code runs on your machines, could
some of you run it and let me know how fast these terrains
render for you guys? (render time is displayed on the top
left corner).

I always get around 1.0 to 1.3 seconds per map.

I've got a 180Kb Exe this time, but no source, sorry. (It's now spread across two files)

I want to add buildings/walls/forts next, but I should
really get going on the actual game now eh? I've been
messing around with this land generator for far too long.
