Nice collection for starters.
IMHO, I would upgrade on the 1.0 Clown. Seems a waste of good females just to make Hets of the same. Generally you would want to pair a higher powered male to a female. Pairing a $400 1.0 Clown to any of your females (except MAYBE to make DH animals) is a waste.
With the Pastel YB, Cinny YB, and Lesser YB, I would really consider picking up a 1.0 GHI Pastel or something to make some cool GHI stuff.
