Sorry it's not right. Please have a look at the examples in the original post try and redraw them as feminine
I definitely like this. A few things would improve it for me: Remove the circle - I just want to concentrate on the helmet for now try & braid a part or all of the plume can you angle it slightly so a part of the open face can be seen (like in the examples in the Original Post) You may want to extend the nose guard slightly so it looks more spartan-like Add some slight wear/tear/weathered texture to the helmet like it's battle worn
This is what a braided plume/mohawk looks like BTW https://www.google.com/search?q=bra...PbCoSCfKc6E9WoxNMEcfu71tHBNJ2&q=braided plume
I like the eyes on this and the general shape but it still doesn't stand out as overly feminine to me
