I think, with that pair[stunning boy, btw] you're likely to get the same colouring as all those pet shop PK's - the colouring both you're male and female have. I have two of them myself, and don't get me wrong - they're gorgeous, but there's soooo many of them. Why not try and find a different coloured male/female and try to enhance a different colour? You're male has quite a lot of red, rather than the blue, so you could try to enhance that.
