Personally I don't find this a bad portrait at all, for sure Jorge has an interesting face and the surroundings give some context.
Postprocessing could have improved the colours considerably. Also, but I am not sure it would work in this case, if you work with lightroom acting on the greens (desat, hue shift, luminance) could have diminished the prominence of the chair without compromising your main subject.
Given that acts on the whole image, it's probably legal as per advanced editing.
This definitely needs a crop to get rid of all the space above the head. Good choice using a shallow DoF to blur the busy background. Try to find a simpler background to let the subject stand out more. He does seem to be darker than the background. Possibly using a reflector could help him to be lit better.
