A very colourful and dramatic M83 Ergio.
I don't mind pushing up saturation for effect, the punters love it and so do I.
Noise reduction is a must and you have done well there.
Some might mention 'black clipped' but I am not an expert on that front.
Sharpening (deconvolution) must be used with discretion to avoid adding false detail.
I think you probably have pushed that to the limits (in a good way).
It would be interesting to see your PI work flow.
I like it and well done
