I do portrait photos with an APS-C around 200mm. I usually focus on the person's eyes.

however, I am not happy with how sharp many of the photos are. how do I improve  the sharpness? I understand that I might be able to improve the sharpness by buying a prime lens.

is it possible to improve the sharpness by switching to a 80mm lens? (the stock lens that comes with the D3400)

will I get better overall sharpness if I am close to the subject or far from the subject?

are there any other functions on the camera (other than the focus) that make the image sharper overall?

Depth of field use a smaller aperture

Shoot faster shutter speeds

use a tripod/monopod

image stabilisation

Improve your shutter button control ~ roll that button don't jab it

use flash

Switching focal lengths i.e. using a 50mm or 80mm will certainly work but only in terms of allowing you to reduce camera shake.

Play with the settings and look closely at the photos. Are you off on the focus - ie is there somewhere that is in focus, just not where you want it? or is there nowhere really in sharp focus.  The suggestions above are good too. I am sure there are plenty of tutorials on the web talking about focus for portraits. Try a tripod and mirror lock up and timer and live view zoomed in focus on a static subject to see what the lens/camera is capable of.

You can make things look sharper with various sharpening in post or in camera, but you should first find the sweet spot settings for your lens/camera and start with the best image you can get.
