What stands out the most are some instruments like the keyboards and some trumpets that just sound very corny. I'd work on giving more personality to those for sure. Vocals sound great, and bass/ percussions are working fine. So I kind of gonna say something daring and guess your stems are a mix of pre mixed stuff combined with actually written/performed sounds with very very stock sounds. Nothing wrong with those, to be fair there's a few popular songs on tik tok with very prominent, corny ,stock sounds. just from a engineers perspective, You're gonna get some frowns thrown at you. but will the average Karen notice? not likely.
