Continuing with my comments from the other three pics, I prefer this less-centered crop. Diagonals of the web lead nicely across the frame and the bokeh (as usual) is pleasing with this lens. I think you can crop the last 20-25% from the left, since the additional web falling out of focus adds little.
Colors look good. Sharpness is not quite there. I think this is a focussing issue since elements of the spider and web are sharp. I think you want to manually focus on the head and try to find an angle that shows more of it.
Macro shooting is tough and I personally fiind it frustrating, requiring a lot of patience, great light, a bit of luck (in my hands) and many images to find a keeper.
