i can't give you a suggestion because there's a million things i could suggest! you need to do some research on morphs, pairings, and figure out a direction you want to go with, because these animals and all their babies will be with you for potentially their entire lives; you need to like what you produce.
go to WorldofBallPythons.com and start browsing and typing stuff in, or play with the Genetic Wizard. this is how i learned about morphs and what morphs i want to work with. you have a lot to learn and a long way to go, and that website is STUFFED with info.
