Well, i was a bit bored, and drew something in paint. This is it:

Maybe it would be good for an INF map.

And yes, it is a CS map also. But, i don't play cs ;)

EDIT:
Uhm.. i had a little time, so i played with polyworks, and this came out:

Do you like the shading or it still sucks? :) Ofcourse there will be a mansion on the right "hill" next to the sewers, and of course a lots of scenery.

Is the mansion gonna be really big or about the size in your picture?

Big, ofcourse.

EDIT: new image in first post, etc..

The shading and colours remind me a little of Boxo's style, it looks good.
I think you should make the low tunnel less straight because otherwise it could lead to lots of spraying and lagging. Make the terrain a little more hilly too.
Nice work so far, I think this map has potential...

Yeah, make both passes more hilly. And what's that square-shaped ledge in the right side of the right tunnel drop? You should try to make it look less man-made ;-)

i would've made the base, but seeing as that part's already done, i can't do anything besides scenery. the reason being is that my 6-year-old comp can't handle doing box-shaped polys in mapmaker, otherwise i would definitely enjoy making the house part of the map.

down in tunnel is camper place :s

Thanks for the comments!
I want to tell you some ideas about the "map":

The tunnel under ground will be sewers (made of concrete), so that's why it's so straight, and the box is a service-room or something like that. Besides, it helps soldats to get to the top -_-

The sewers will have several "columns" with bullet collide, so it can't be sprayed or camped that much.
