Steel beam cantilever with small backspan

Long story short, I have a situation where the contractor started building without sending me shop drawings for my review. Also, I am dealing with existing conditions. So the columns you see are where they are and they can't be moved, and new columns can't be added.

This is a structural steel framed balcony with concrete over metal deck. There is an existing building beyond (not shown) that runs the length of the balcony. The end of the balcony is cantilevered, and because of life, one of my cantilevered beams is going to have a 4.33ft cantilever and a 5.33ft backspan.

My deflections look OK, but I have the possibility of uplift at the end support. I am worried about it. Should I worry about this? What can I do to help the situation?

The beam sizes are W8x15. TIA.

Less concerned with uplift conditions with steel... it's generally pretty stiff and usually easy to connect to.

So strange to see the singularity approaching while the entire planet is rapidly turning into a hellscape. -John Coates

It is difficult to relate your printed output to your sketch, but if the maximum deflection is 3/16", I don't think it presents much of a problem.
