Since Revelation, EJ's pencilled SL:Jazz, an issue of the Ongoing (issue 7 I think?), and SL:Prowl. He also did some of the pages for AHM.

His style HAS changed a fair bit since Revelation though. He seems to have been going for a Mike Mignola style. YMMV on that.

Megatron Origin was never really that well received. It was also originally supposed to be 6 issues, not 4. I'm pretty sure it was originally pitched to Dreamwave.

It also had a pretty bad problem with the colouring. It was WAY too dark and murky for the single issues. This was somewhat fixed for the subsequent tpb release. It was also back when Milne didn't use much variation in his line-weight, so foreground characters and backgrounds all melted into one mess of a panel, further obscuring detail and making it a chore to comprehend.

Honestly, the 2 recent flashback Ongoing issues did their background way better than M:O did (22 and 23, I think it was?).

So it's far from just you on this one. It was a mess all round, really.
