Composition looks great, horizon looks level, and the wire is an easy fix in photoshop. I'd say the one recommendation would be to choose a different time of day where the lighting is more even across the front facade of the building. The left side is currently in shadow with the tree casting a fluffy shadow along the front steps.
Thanks!
I'll try again a bit later in the day sometime and see if I can at least get rid of that shadow. Lighting is tough on this building due to its alignement and large number of trees. Maybe an hour or so later in the day will get rid of the tree shadow. But harsher light. Afternoon light pretty much year-round leaves a shadow from the large tree on the left (south-ish side of building).
Still need to improve on my 'shopping technique, as I can see where I've removed the wires each time I try.
