Let the market and audience decide your type.
If you feel really strongly about your brand, but the audience or public isn't receiving the message- it's time to reconsider. Sometimes the brand you start out with isn't always your first choice and it may seem less exciting.
Your brand is there to help you land roles, once you get enough recognition with your brand then you can branch out and try new things.
The audience will start to follow you and become fans due to your previous work. When you have enough of a following, you can branch out without losing fans or the value put behind your work.
Instead of trying to force a brand that is not working, it is easier and a lot more satisfying to let the audience decide how they perceive you.
That's why it is important not to rush into your brand. You should try things out first and see how you feel about each character type before publicly branding yourself as one type.
Remember to ask friends and family how they see you, what characters they see you play and watch those characters on film.
Imagine yourself in those roles and with that brand.
