There's a chance of the short-arm clothesline & pose, I'd just make them separately. As it is now he can hit the DDT as a reversal or out of nowhere without having those extra moves attached every single time.

Or maybe just add the pose, where he circles his arm in the air?

Fantastic job of Jake's DDT. Any chance of adding to it, maybe make it longer? short arm closeline, signal and then DDT??

Wonderful DDT-Great job!

Fantastic! Thank you!
