It looks a little bit wrong for smooth sumac, but I can't say exactly
how it looks wrong.
I have smooth sumac against the south side of the house, being a
lightweight tree. Its disadvantage is that it dies and/or breaks
sort of randomly, but it gives a nice screening shade pattern
in the summer. It sends up all sorts of shoots except where you'd
like some more. Lawn mowing takes care of them in short order.
Some of the trees have berry bunches that last into the next spring,
where early Robins and late Cardinals get them.
When they mature, they're pretty tall and leave the lower altitudes
leaf-free, so you get a nice old-growthy forest in a few years.
