Leaf, bark and the tree itself says it's a Norway. Looks like a decent tree from the pics. Also looks like some nice pruning cuts, I wouldn't do too much more to it, like you said maybe thin out a few branches.
Thank for everyone's insight!! I am now sure that my tree is a Norway Maple now that I hear from you guys.........and yes the tree does shade out the ground below it to the point where its hard growing grass under it. I do intend on thinning it out a bit. Like cutting every other branch off going up into the canopy.
