I like these images of you:
Better than your newer ones. There seems to be too much spacing in your newer photos around you and you are not framed in a way that makes me look at you for longer than a second. So I guess this isn't an issue of yours but a photographic/Crop/Framing issue. Also the lighting in the tunnel is terrible its casting too much of a shadow on your face.
Keep shooting with photographers and practicing and only put the best of the best up. Get an eye for detail when it comes to what you put on the port because its not just about you looking pretty its also about the quality of the image as well
*all of this is a personal opinion and should be taken lightly*
