I love the Igor concept art. It's a shame they decided to scrap the idea of him being Long Haul's head. I have to disagree. I like that they went with a more alien and sinister looking head for Laserbeak. This one just looks too simple, and not alien or threatening enough.
dang i like about 90% of everything he made. esp the prime/trailer work are very nice.. i really wish they used that to fight megatron or something =\ i don't really like the flying thing though.. looks a tad odd
