Help recreating lighting

Hello!

Recently, I made a teaser of one of the games I was working on with my team and it turned out great! So great that I somehow managed to perfect the lighting, and now I’m obsessed with trying to recreate it, albeit to no avail.

Getting to the point of the post, I was wondering if a Lighting Expert :tm: could help me possibly recreate it, or help point me in the right direction? Help would be much appreciated!

Thanks!
