ABSOLUTELY. Try for as many roles as you want!
There is no age restriction or gender restriction for any role. A feminine voice or feminine-presenting voice does not restrict you from playing a masculine character or vice versa. Your accent, whatever it is, doesn’t restrict you from any role. You could be anyone!
