Congratulations in advance on 1,000 downloads. (It's at 933 at the time of this review, but I'm sure it's due to happen soon.)
Make some single player maps. Then it won't feel like your detailing skills are being wasted when most people won't notice them in a EMFH game.
Oh yeah, the maps. Your two new entries are fantastic. And they aren't arena maps, so I'd give you a 6 if possible for actually taking the more difficult route.
The fifth and final edition of my second multiplayer map pack includes 24 maps, all varying in size and layout. Version 1.4 includes 2 new maps.
