Is that a M-MIMO antenna? Looks pretty square for a standard Sprint set up. Or could be one of those 9 beam antennas too

Yes on the left side of the facing two antennas.

This is pic on the other side when i was drving back from downtown.  Guys where up there working. I think on one of the pics you can spot them.  I do have to say, I'm quite impress with myself. Not easy to take pics while driving 55+mph. ?

 

These are the other two pics I took while driving.
