Hi Carlos, I like your people shots but IMHO some of them could be improved. Like Australia, the sun can be very harsh after about 10 a.m. and shadows are dark. With photoshop you could adjust this simply by using Image/adjustment/Highlight and shadow. I took the liberty of making some adjustment to your image but unfortunately, photoshop chopped a little off the brim of the hat (It happened twice so I didn't start over again). I first used the highlight and shadow command then I went around the portrait with the pen tool to create a path, then Inverted and blurd the background more. This is the result, hope you like it.
