There is no exif, so I could only guess.

It appears the photo was taken with flash and with a relatively long exposure time, so that the photo is composed of a sharp exposure (from the flash) and blurred exposure (from ambient light).

Depth of field is shallow, but you can argue this is a good artistic effect. Focus is accurate though.

To improve, one can increase ISO, or set the camera in M mode.
