You got a little powerhouse there that can make all sorts of cool things. My best advise is to browse pictures of combos and either make a pintrest or download pictures to a folder of ones you especially love. Try to nail down what types of projects you are really interested in the most. Your passion about your project is more important than any other factor.
That being said, a couple of morphs I would suggest at looking at to possibly include are GHI, Red Stripe, and Mahogany. If you can find a female that is at least het Hypo if you are trying to keep that going, you will have a much quicker progress than trying to breed hets and then next generation breed back to dad or sibling to sibling. Sometimes you just can't find "the right" female that has the ingredients you need, and you have to go that additional step, and that's okay.
The reason for those particular suggestions is you have a lot of different brightening morphs in there and no darkening. Sometimes to bring out the most gorgeous combos, you have to come at it from both angles, add as you subtract. So GHI or Mahogany can really help bring back some of the deeper hues. Red Stripe brings out some amazing reds in combo with what yours has.
