Looks cool! In jet mode i think those wide fan-like wings are what throws it off the most. Maybe paint the rear (clear) parts of the jetpack red too but this is just nitpicking on a fine job.

Gok, that Jetfire reminds me of the recent deluxe bomber Megatron we got.

I am also getting an IDW Metalhawk vibe with this Rodimus head on the Jihaxus body..
