Agent 44 just keeps knockin' 'em out of the park in my opinion. As an artist, there is nothing sweeter than coming up with an awesome concept and then executing it beautifully, which he seems to do with startling frequency. His latest pieces, which he has produced as prints, are riffs on the Cars world. He hones his skills by producing the regular series of Missile Mouse and has been included in several volumes of the Flight Anthologies. Not to be overlooked however is his concept work on major film productions like Rio, Ice Age and Horton Hears a Who. I don't know what I'm missing, but I'd love to get to the sweet spot that Jake has found.
Your time would be very well spent by perusing his site and his blog. Great work Jake!
