Eyecandy: P4ul's levels look nice, but as St. Louis says the eyecandy tends to hinder gameplay. Snooze and cooba are good at eyecandy, but I'm going for Splash. The eyecandy in his later levels was exactly the way I like it.

Theme: This is mostly relevant to singleplayer where you want to immerse the player as much as possible. EvilMike's done a great job at that with his packs, but having catched a glimpse of what could've been Tomb Rabbit 2 I have to pick Kejero here, who created some incredibly atmospheric levels that managed to immerse me really well without even having a story.

Gameplay: [It is] stripe.

Placement: wtf?

Fastest improver: That's a tough one. I think I'll go with Ragnarok and go for Birdie here, who seems to have disappeared from the community recently though
