Among Friends

So this is for TTrain427's Digimon Shade Virus competition [link]
I'm not entirely happy with the result but I can't quite pinpoint what I'm unhappy with. This was one of my first attempts at an interior perspective drawing, I'm not sure it came out as well as I wanted, anyway I hope TTrain427 likes this ^^

The characters featured (clockwise) are: Archmon, Train, Dex, Kaycee, Nyxmon, Kai, Impmon, Sacomon, Pyromon (in training form of Lanternmon) and finally, Zeek.
