Turning and finish look good, sorry but the kit's not one I'd choose.
I think what Brian is referring to is the "dip" that looks to be there near the cap, but looking at it to me it looks like shadow on the pic rather than a dip.
Great first effort though, bloody sight better than my first. I still have mine as a point of reference, keep that and you can see how you progress over time.
Good stuff !
