Your pullet's crest looks acceptable to me. The standard states that it should not obstruct vision like polish or silkies, but sit like a cute feathery hat on her head. The top cream legbar hens have crests similar to hers. As to her color, she is gold, or more specifically, golden crele legbar. There is an effort to get the golden crele color accepted into the standard of perfection along with, or shortly after, the cream color.
I attempted to make a small video about how to sex cream legbars last month. It's a bit rough, but it's the basics.
And I've got this basket of various different male golden crele legbars. The down patterns for golden crele and cream legbars are identical.
If you see a big headspots that goes outside the v on the head, faded body striping, and less defined eye markings, then it is male.
these are all females. Notice how well defined their back stripes are, like chipmunk stripes. What headspots appear are very small and entirely contained within the v on their head stripe, unlike the male. Females have very well marked eyes, like they are wearing mascara or painted across their eyes, the male typically has less defined eye markings, or sometimes no eye markings.
