your males are some how not powerfull enough. i think you should sell 1.0 pastel,1.0 hypo,1.0 het albino, 1.0 blackpastel and buy a power house male,
maybe a enchi vanilla YB, or a breeding size super vanilla pastel, super fire pastel.
as a female i will go for a leopard pastel, vanilla enchi, mystic enchi, specter blackpastel, gravel, spark.

just my own taste. hope its helps
