Looks like a great start to a breeding collection!
I don't see anything in that normal girl you posted. A dirty belly like that is pretty normal for normals. The head spot is also really really hard to see. A lot of normals have a tiny/barely visible head spot, that's nothing too indicative of a possible morph.
Check this girl's head spot out, she's nothing more than a normal, she's from a pastelxnormal pairing.
