How to improve shadows on mobile

I’ve tried many ways to replicate the shadows of my demo I made, and making a mobile game with it. the problem is that I used a computer/console for my demo and mobile for my game. I also made my own level so I cant recreate the default lighting used in the blank template, because I’m using the third person one.
ive tried playing with bloom etc and nothing has changed the shadowing much

thanks, max
