Should i go butch when im super fem?!?

so im straight up FEM. like fem fem fem, but only because im used to it. im bored with looking like everyonee else, and i want to try something daring. not like shave off all my hair look like a biker man butch, but like short skater hair with beanies, skater boy clothes. stuff like that. i've always wanted to but never had enough confidence. also i have large and a chubby round face, but im pretty skinny. ive never seen a butch girl with s or a round face. im 15. does anyone have input and or pictures of girls like this? i just dont want to hate how i look afterword.
