Great to see you're back. I think your coloring's improved a hundred fold since the last peice I saw. It's alot more vibrant and defined here. Doing commissions yet?
You know you're getting better and better at this, right? A real alternate mode, with a real transformation that actually works - fantastic! My only minor criticism is that he looks ever so slightly chubby, an unfortunate consequence of having that cab as his chest. Maybe if the arms were brought forward a bit...? Great colouring and design though - more please! Oh, and if you ever think about drawing an Alternator or two...?
I always viewed the Argosy as the best modern incarnation of Prime, and my vision of him was nearly identical to that, with the exception of the grill sliding in and the sides of the bumper folding to the sides to give a more athletic look, and also that the sleeper section only folded back half-way, leaving a hood, but a hood that housed missile launchers on either side of Prime's head. Between you and Don, I'd say the fandom has more talented and passionate people than Pawtucket does. Another excellent job.
