Color or no?

Sometimes I just can't decide if I like the color or the black and white version better? 

I am currently trying to teach myself photoshop. I think I would rather take chemistry again. It is so confusing. When I finally do think I understand something I realize that I don't and it has to 5 more layer to the action.  I think photoshop may be above YouTube videos for me. I may need to take a real class.
