Very nice map. A couple things bug me, though: The barrels are all too wide and do not align properly with the barrel top texture. The ladder in the base is very large and goofy looking. It takes away from the visual quality, I think. I think it would actually be better without it. There's plenty of room to just build a ramp right up to the flag, and it would make it a lot less awkward to navigate as well. Most likely the people trying to get the flag from that angle (instead of t he other jumps available) will be new players, so they'll need all the help they can get.
I'd say just convert that section of the base into a large hill that leads right up to the flag.
