Well,they aren't the best in the worl, but I have seen worse. I'm sorry if I seem rude, but i'm trying not to be.
1. There are Wayyyyy to many people/ pokemon in each one.
2. The ground in the first one isn't very orderly, It looks really wavy in some parts.
3. You can still see the outlines (white) of some of the people.
4. The contest judge lookes extremely out of wack.
5. The red and blue one looks like one big room under ground, No walls on some sides, no dividers.
The Base looks pretty good, but the others are really off. My sugguestion is to use a tile set and really place everything/one in the perfect position.
