Nice looking image. It has a painterly quality about it. I tend to agree with the suggestion of cropping a bit of the top, and probably a tad off the left to maintain a 2x3 ratio. It's lacking a lot of fine detail, which probably accounts for the painterly feel, and may have been due to the tc... but that's a guess. This would probably make a lovely print... possibly on canvas or with a brush stroke coated applied. I could easily see this hanging in a beach house.
Hi Bob, Nice capture but agree with cropping the blue off the top and cropping some off the rt just past the blue in the lower rt. I don't believe the slight softness is from the 1.4 TC due to my using your exact setup many times with images coming out tack sharp.
