will one creative subject affect my chances of getting into a good uni for law?

hey guysss i need some advice on a level choices, i really want to go into law and im hoping go to a russel group uni.For my alevels im taking econ, politics and either psychology or art.
I really enjoy art and its a break from essays and equations but im worried that if i take it it will lessen my chances of getting into a good uni ifykwim.
Psychology seems really interesting and i also dont take it for goses btw.So yeah basically will art be a bad choice for law in the future? also if anyone takes both art and psychology which do u prefer?
(im predicted an 8 or 9 in art alsoo)
