Mirian Chicas has a calm dog and used the opportunity to capture her friend very nicely. Using the ambient light from the window works well and the dog's profile creates a strong composition. Looking at the full sized file the background is very noisy and there are digital artifacts (or halos) around the edges, this could just be a result of the particular camera and shooting at ISO400. Next time if you have the chance to remove the lampshade in the corner it would clean up the background. Overall this is a nice capture and one you should be proud of.
