Hi Osvaldo: Lookng to your pic I get an strange feel. I mean all is in there, a good subject, nice sky, directional light, but it looks incomplete, not really finished. Perhaps is the lack of definition, the horyzon is in the middle, the subject has not enough relevance, why mot try to get back and try to approach more and to fill the pic with the subject, there is a concept "work the image" it is to get there and try several angles, moving around and taking all the nice pictures after all you have a digital, so it is nearly free to work the image and play around with composition Keep doing.
