Bowser's Kingdom Characters

This is the first major picture I drew using a tablet.
For those of you who aren't familiar with "Bowser's Kingdom", it's a Flash series by Andrew Raskin starring a goomba named Jeff and a koopa named Hal who work for bowser to capture the princess or defeat Mario (they always fail). Check it out on newgrounds.

Here are the names of each character:
Goomba-Jeff
Koopa- Hal (doesn't get paid)
Piranha plant- Steve (Total doormat)
Lakitu- Rick Finklestein
Hammer Bro- Paul Hammerbro (Obsessed with hammers)
(top right corner)- Karate Duo # 1 (two asian stereotypes who fight for profit)
Thwomp- Inaudible Thwomp (he speaks so fast that no one understands what he's saying.)
