You look nice

Try to relax a bit and try to feel feminine ... as a natural feeling ... it will show to the outside.
It may make for an even nicer look.
You could try voice training, its reading a book for example in a bit higher voice regularly. It may take some time, but with some people it may show results fast, for example people having experienced voices from singing.
Just don't overstrain your voice, simply stop then.
