When asking question like this, I would suggest dropping all the line created names and just use the common ones. You are breeding a Super Fly to a Fire. :)
The only Pastel BlkEL I have seen was at tinley a few years ago and it wasn't even proven it was pastel. The one thing that stuck out about this snake being odd and the camera didn't pick up very well, it the back of the head. Notice the whiter spot touching the yellow on the back of his head? That was a night and day difference in real life, like pied white. I don't know if that is a Pastel BlkEL trait, I don't even know for 100% that it is in fact a Pastel BlkEL (pairing was firefly x fire), but your pairing could shed some light on that
