I have completed 2 maps on farcry now and i must say the detail level is amazing. Here are some pics. first map is a huge satelite dish inside of a custom mountain that looks like a tremors worm coming out the ground, also a custom waterfall and a massive bridge with a robot facilitly on it. strictly aesthetic. the second map ive made is a rooftop theme complete with a bunch of harrier jets, comanche choppers and f14 fighter jets flying around.
TOYBOX! Damn fine map in my opinion. I assume you can run along the pipes? As for the jets, I wouldn't put them right over the middle. But that's just me.
