Nice try. Not a sky blue normal, but an opaline cobalt. And the yellow face is visual spangle. A bird cannot be split to spangle. It appears to be opaline recessive pied spangle yellowface mutant two sky blue. I cannot tell if the wing markings are black or some other color.
They are at the moment a greyish/black color, maybe after her 1st moult they will go darker?, she's only about 4 months if that helps also, also their is no sign of any iris rings not even very faint ones coming through on her, the other 1 though who i think is the same age has a slight iris ring which i can see developing, hope this info helps in finding out what she is.
