Specific Improving a picture for a birthday gift

[JFSpellman]

Hi, all -- I joined the forum looking for an edit. I want to take the attached picture of my friend Jay, slim down his gut a bit, make his arms and shoulders more muscular, crop and re-center the image so there's less foreground dirt, and remove the seated figures in the background. I don't really know how do-able any of this is! Huge appreciation for any assistance!

One version...rather than remove the spectators, I blurred them out...need an audience for this home run...

OMG, JeffK, this is fantastic!

Awesome! And please pass on my birthday wishes!
