Western Dragon Taur. All the noodle.

what about a tall/long dragon neck, and also some big tusks?

Cool nice Mane.

But him need a friend. Maybe snake tail. And need cool Horns

(Sharing my suggestion from Twitter here too if it's cool!)
How bout a big eagle or corvid head to contrast that lovely mane!

As for how to spice things up?
Maybe a hefty/hyper draconic and equine style shaft with similarly huge and taut balls to match~?

I'd second bird head, raven surely sounds as an interesting mix up to the fluffy mane.

Let's get those arms converted into big bat wings!

Eagle or some kind of avian head sounds pretty cool.
Eastern noodle dragon also sounds awesome

Another pair of arms (and pecs)

I think he should keep the human head,but maybe he needs another...?

The upper body should change too

Make him into a murder multihead and crew upperbody

You meant to say 'Crow', I presume?

Grows two extra heads becoming a cerberus?

ohhh i second the cerberus idea, esp with long necks

I'd be down for a cerberus!

at least one more head and perhaps two more arms

Other than maybe an anthro torso and head this is perfect.

Everyone seems to be suggesting 'bird head' or something, so I'll go with that, and add this:

Make his upper body split into two upper bodies. Or rather, two chests atop one belly, like a 'Y' split in the middle of the abdomen..? One of them with a bird-beak and human rest-of-face, with fluffy, feathery floof around the neck and shoulders. The other one head with a lion muzzle/snout and human rest-of-face.

The splitting of the upper bodies is slow, so we catch him / them in a moment where the arms on the inner-edge of the split are still connected. This will make both of them feel like they are missing an arm, for a little while. Instead of the arm being ~missing~, though, it is just tethered / anchored into the other person, making it unavailable.

Perhaps the TF stays that way, or perhaps the stage after that can complete the splitting of the two upper halves.

Maybe dragon head on the front of lower body, makes it feral taur.

Agreed!

I second this

Put a little bit of Hydra in there, with the loooooong necks. >:3

Give him a second head, another pair of arms, a second version of himself sprouting from the taur with the other changes included, a snakedick

I do like the idea of a maned dragon as many others have suggested!

All the people saying multihead, why stop at two? Let's go full cerberus >:3

Maybe you could give him 4 more arms?

Bull head?
