 A quick glance, this picture looks pretty good, but on closer inspection, you can see we have these mega hot pixels that are quite annoying. So I'm going to show you how to get rid of those. We're going to go to Select by Color Range, change it to the Eyedropper with the little plus sign, click on a bunch of the blue pixels, hit OK, go back to Select, go down to Modify and choose Expand, and expand that selection by one pixel, then go to Edit, Fill, Fill with Content Aware, and there you go, it's like the hot pixel never existed, and then you would just repeat that for the red and green hot pixels, and you're done.
