Hi Diego,
Aesthetically that's a lovely colour palate and a well balanced image.
However, there's a wierd oversmoothing (too much NR?) and over sharpening thing (overcompensating?) going on imo. as there should be lots more detail in this thing.
When I was first getting started in NB Strongman Mike quite rightly pulled me up on a similar "colour by numbers" appearance critique, which I eventually resolved after a long hard look at my workflow.
I'm thinking there's something similar amiss here with your workflow as well, probably early on in the processing.
Having said all of that though, your colour choices are terrific imo, well done!
