It will take a few generations to create DTPK.
Color wise, she is a dragon but he is regular. You will have a mix between regular PK and HM, PK and HM geno (longer dorsal), Half dragon, non dragon (not sure which combination of color and tail type).
You might not get all the above features and might have to do a second batch of F1 (I usually do 2 - 3 spawns, 1 - 2 weeks apart. Then I cross between batches). Inbreed the DTPK genos in F1. Then inbreed DTPK of F2. Cross breed DTPK F3 to a new PK and re-do the above steps.
It's unadvised to breed DT x DT for 2 generations. So when working with DT, you will always have to cross breed to a single tail, preferably to a new genetic set (not from your line).
I love their colors, so I'd say go for it.
