Best render? (Patreon)

I have a lot to learn when it comes to rendering models so I'm trying out some different options. Which do you like most?

I want to make sure the render shows as much detail as possible! I think option 4 is the best? But honestly I've been tinkering with this for about an hour so I probably need to come back with fresh eyes to make a good vote.

OPTION 1 : Current Render Choice

OPTION 2 : Brighter version

OPTION 3 : Black and white 

OPTION 4 : Brighter black and white
