Some thoughts and advice:
Most of the DM maps are incredibly huge, which makes it a pain to fight. A special mention goes to that pink/purple map with the soft music, mountain and trees (which I forget the name of). For the next version of this pack, you should concentrate first on making the map layouts easier to navigate. As much as I like your decoration style, which is very creative, it's not fun to get lost in a map and wait 10 minutes to get a single frag. PLEASE keep this in mind next time. It's for the best, trust me on this.
Of course though, with layout reduction comes reduction of excess items, but work first on wrapping up the layouts first.
EDIT: By "wrapping up layouts", I mean take the look of the map (or the aspects you think make the map different from the rest of the ones in the pack). Now let's say the map is a birthday cake. A cake has (of course durr) the cake itself, the candles and maybe plastic decorations. You don't need (or rather shouldn't!) eat the candles/plastic decorations, so you take them away and THEN eat the cake. Tastes better, no? And one slice at a time, too. You don't wanna eat the whole cake at once. It'll do... stuff to your system.
