The image appears to have been shot in low light or underexposed, it's hard to know since no explanation or metadata is included. When that happens with my shots, even at low ISO, I use Topaz denoise and most often it is an overall improvement, you may want to try that first. Often I'll simply hit the Auto button in LrC to see what it does and adjust from there. If not using the Auto button I'll first adjust the whites based on the histogram, pulling them all the way to the right to see what the image looks like and then adjusting to taste from there. After that I'll pull up the darks based on the histogram, especially if the shadows are blocked. Then I'll pull up the midtones using the Exposure slider. If there is white in the image I'll carefully check to ensure that nothing is blown out and that the white is actually white, not gray. All of this is done to my taste and to what the image will allow me to do. I tend to like bright photographs but I see a lot of dark photos on this site so obviously many people like dark photographs. I'm always looking for that "bright, happy world" and that is what I'd like to convey with my images so I process that way. I don't mind the lighter spot (it is, after all, not a studio background) in your image but if it were my image I'd try to change the purple hue of the brighter part, although that might lighten up a bit if you were to increase the midtones. Processing is a matter of taste to some degree so if you are happy with the image then that is all that counts as long as you are not entering it in a competition of some sort, where processing then does matter a lot. I cannot process the image to show you what I might do since I cannot download it, apparently the moderators can do that.
