First, the photograph is not sharp. Analysis in Adobe Photoshop using the Camera Shake Filter indicates significant camera movement while shutter open. Settings in CSF allow adding some sharpening anyhow. I did so. I do not go into the detailed CSF adjustment here.

I did what I could with basic tweaks in Adobe Camera Raw and in Adobe Photoshop. The image did not look noisy, so I did some sharpening in ACR and then later in PS using the High Pass Filter (which detects and sharpens only edges).

I increased exposure in ACR. In PS, I used the Levels Adjustment tool to set the black point and to adjust the mid-tones.

Boy, I’m impressed with your processing ability! Nice job!!
I speak in general terms here, and all the processing I did involved only simple actions.

Cropping the image put more attention on the main subject while bringing visual balance to the image.

Obvious suggestions: Take more care when pressing the shutter button to avoid introducing excessive camera movement. Shoot at a faster shutter speed. Raise the ISO a stop or two to achieve this speed.

Others here may have other useful things to bring up.
