Hola, Juan Carlos. Really nice sharpness and exposure on this one, and the composition looks very good to me. The only thing I'm not crazy about is the background but I'm guessing that unless you brought your own paint and a brush, you didn't have much choice :)
Way cool! Apt title too. I agree with the tighter crop suggestion (but keep the same basic comp). Could the area around the eye be selectivley lightened just a wee bit?
