I am on a different computer at the moment, so I can not be 100% sure. But the colouring looks great to me. I also like the added touch of the bottom panel filling the whole page, and the top 3 panels layered over top of it.
For clarity, I meant you did a very nice job of depicting nasty looking mud. The mild rainbow of colours give it a wonderfully evil oily/slimy appearance and the consistency, and sound effects bear that out into a horrible bootsnatching squelching mess. I almost hate to say it of something as mundane as mud, but I think it is one of my favorite colouring jobs of yours so far.
I've been following your comics for a little while now, and I'm a big fan of your imagination. Just thought I'd introduce myself here. Looking forward to wherever you're taking this story!
That's my electrical grid right there. From an old (but awesome) dam to an old (but awesome) powerhouse into old (and not awesome) wiring on two or so fuses house.
