Looks like this could be improved by using a larger file size, as you point out. The heavy crop also has a negative impact on image quality. I like the eye contact and wing position.
Alfredo, as a BPN paying member you can always upload directly from your computer - that would help with your image quality compared to facebook. Just make sure to resize to 1024px max on the long side and keep the file size under 200kb.
Anyhow, I like the pose and the staright-on look. Squarish comp looks good for this image too.
