The Dragoon does have a big hump in T1. It seems more pronounced here. I like it quite a lot.
Some considerations ...
* There's a lot of bug influence in the T1 designs, the claws do clash with that. I agree it needs to carry it's weight convincingly, but I'm not sure this particular design fits best.
* I like the claws, but for consistency it should take it all the way through the evo chain, if the goon has it the rant should also have it, not sure how that'll look.
* If sharp tips for feet, it might appear to float when shadow map res is insufficient, though that seems a nitpick.
* BIGGER TEETH! I suggest some low poly triangular ones (it'll look fine when normalmapped)
I did some of that before and found this basic formula gave the strongest design

* They might be murdering machines, but keep some of the cutesy proportions, that's really one of those things that makes T1 what it is.
* Tapering of the middle section on the front legs looks a bit strange
* Using more conic and straight edged spikes on the head might work better, having some geometric 'decisiveness' often helps a design.
