British Accent help (UK based videos?)

Hi all

Brand new on the voice training here, one thing I am struggling with is how harsh a British accent (fakkkin saaf eaasturn) can sound and a lot of the big youtubers are American which I find can be a little unrelatable at times. While doing an American accent is actually really easy for me, it's the Brit words that pull me back down into my bassy voice :P

For any other UK people here, did you have any particular resources that helped you with your voice journey?

Thanks
