Those look alright to me. Was the mom the Leo or marble?
I think they all look good, seems most that have grown out rays like this dont see a ton of change but also most sell them a few times and they get lost and i cant say ive seen to many really large ones. Agree with number 2 looking very nice.
Tom (Mr Allgood) has a large female. CB by CoolMBU. Dad was Marble, mom leo.... Could check his pics to see what they look like as adults. Sold for around $500 I believe but the blackie market was much stronger then.
Personally I'd pay more for pure Marbles. Especially if they're similar quality to what you've produced. Probably quite a bit more.
