Hi Neil, I received your file through e-mail. It looks fine to me, I'm not sure why you'd be worried about that.

But if you do want a smoother shape where those blend surfaces meet, you can probably get that by using an option in the Blend command for making a curvature continuous blend instead of only a tangent continuous one:



That will make a blend with a higher amount of smoothness where it comes off the other surfaces. It's normal for 2 surfaces that are only tangent continuous to have a kind of slight interruption in reflective highlights. That should likely go away if you use the curvature continuity option though.
