Amazing art, thanks for sharing.
I agree with Nate the flying vehicle in those pics definately looks like a Blimp.
Futhermore those pictures also look like they are originating from the time/project as the following ones:

The fact we see a Blimp in there makes me think those pictures were done after MO and the "Oddysee" referred to here is actually the Oddworld Movie. Also they look like Raymond Swanland, and he wasn't present during the Abe's oddysee game pre-production.
