I've always loved that one fourth over on the top. The red one in the boiler room or wherever it is. The colors are fantastic and the simple rim lighting on Bats is very eye catching. I'll always say that a simple color scheme will give you a ton more milage on a cover than a complicated one. I can tell you have the same philosophy. These are terrific.
These are some of my absolute favorite cover from the Batman Adventures! I must admit that I had seen your work before this but it was these covers that made me really take notice of Kelsey Shannon as a true artistic weapon!
