Okay, so my first map wasn't too good, but I felt like making another one (hopefully better). But the thing is I need some ideas, I'm not very creative when it comes to making maps. So I need any ideas on cool map ideas and please make them reasonable. Not something like a huge mountain with tunnels in it or something(although that'd be very cool =D). And I need the idea to be not too easy, but not too hard. I'm not a master at making maps, but I wouldn't say I'm nooby =p. Also, I'm not very good with texturing. So I need some texture combos, like wall and floor, to use. And another quick question, there's this one texture I've seen used in some maps for the build wall. It's kinda like shiny, metal paneling? Like this...
This is from sf_crete.

Anyone know what the texture is called?
Anyway I'll pick the idea I like best. So post your ideas up! Plzz =)
