Okay, here come some reviews:
Minefield: I don't know I wasn't able to play that one, I'm sorry
Magic the Gathering: Really cool map, really got the slight feeling of playing magic, it was a bit too simple though :/ I just built 3 towers and they dealt with the enemies before the even came in close range. The terrain could have been slightly better and yeah. That's it. I voted for it though, as I just found it the most creative map.
The Exorcist - Personal Opinion: This map has lots of potential, as many things could have been done way better. Overall I think it's an quite acceptable map, which gets slightly repetive after a few minutes, but is not bad anyway.
Destromath TD: Didn't play it, no offense but I'm just no fan of TD's
Defense Map: Really really liked this map. It was great fun to spam the spells on the units, but in the end I just got overwhelmed by soldiers and archers

With a bit more creative spells, a better terrain, and a bit less difficulty, this would have been my favourite. It was really good nontheless.
Eliminate the terrorist: I just wasn't able to find out what I should do in this map

The title says, eliminate the terrorist, but in the game I was the terrorist

I didn't get why I should find my own bomb and disarm it (which I guessed the whole game is about). So jeah, a better description would have been good.
Tidal Defense: A really really original map, which was refreshing new. It got a bit boring after a time though, as I just always pressed the same button to push them back into the water. It was really great though, my 2nd favourite.
Brambleclaw: Didn't play it as I somehow wasn't able to start it in wc3.
DonDustin: Awesome defending map, terrain was quite good too. It was great fun to push the enemies back, if the heroes had a bit more offensive spells it would have been great. Really cool map, but sadly not THAT creative
Figueiredo00: Didn't play.
Don't get me wrong guys, these are just my personal opinions

I also want to apologzie that I didn't play all maps, I just didn't have the time/motiviation and/or wasn't able to play them.
