He's just voted in an election hasn't he? Somewhere like South Africa, where I think you have to dip your finger in ink after voting as discouragement to people who might think about following the mantra
I really like the vibrant colors clashing against the backdrop in the colored version. Although could edit out the green tint and color correct the hurt finger.
Those two changes aside, really good picture. If it's of you I'd suggest just keeping both versions and using them for different things. Colored for avatars (as those catch attention better) and B&W for gallery, and perhaps alternative covers.
@Denel I went over pixel by pixel in areas correcting it, there was quite a lot of greenscreen reflections. Also I tried to fix the finger but that's a lot of distortion so I ended up essentially redrawing it using your other hands fingers as a palette.
The finger can work but could perhaps use some more touchups.
