Id like to underline a point or two,, your camera is capable of very sharp pix , your lens is also capable of very sharp pix ,
technique plays a big role , in the end product..
and much of that is just
what you do when.
As photo-consumers , we are conditioned to seeing photos actually sharper than sharp,
sharper than your eye can actually render.
If you held a bird in your hand , often you may not see as much detail as a photo of one taken at fifteen or thirty feet!
So.. sharpening procedures often are usually just enhancing the
impression of sharpness ,, because the visual impact of a photos sharpness, has so much mental filtering involved.
Watching a moving series of images also has a degree of mental addition, if you freeze a clip , and look at an individual frame , it doesnt look near as good.
The 7100 also doesn't have an anti aliasing filter , which does an automatic smoothing of images in other cameras.. this changes the look of both sharpness and noise.
Everyone has their own systems for post processing
I like usually two rounds of sharpening of moderate extent each.
upsizing, downsizing , compression etc.
also affect the impression of sharpness, so from your posting here in compressed jpeg its hard to tell how the pic is on fine scale as well.
Lastly , an audience really cares more about content than the photographer may. They prefer to see the folks at the wedding having a good time ,rather than the roaches eating crumbs behind the stove,, or the grooms hair folicles.
