Static Mesh placement, map flow.

[JDCT]

So I started randomly putting together a map, and so far I have the bare bones done. What I really need some advice on, is static mesh placement. I know its probably more of a question of experience, but I can never make them look right... they always look out of place. Should I design the map around them meshes?

Anyway, like I said, I have the bare bones done, some meshes have been placed, no lights, no bot path, no sky box yet. I just need some advice first before I continue. Also, I would like to know if the map has good flow to it, anything would be nice, any advice on where to go from my current point.

I have my map here attached but, I am new to the forums so, if you could tell me how to post my file, t'would be great. or I could always host it elsewhere.

Thanks

EDIT: Oh, nevermind about how to post the file, I see that just attching it works right after you post... ah.
