I am a fan of patterns - so the first shot with its repeating, yet changing lines is great IMO.

The 2nd one shows some detail; however I wonder if it could be sharper? I don't know what aperture you used on the lens, but if stopped down too much, it can lose something. A focus-stack approach could work. (Alternatively it may be down to the limitations of jpeg file-size on the PU website!)

Keep playing, really like these. Really like the patterns in the first and the way the light fades off to the right. Like the shape and form of the 2nd, did you have to lift the shadows in the facing edge, I can see what Andy means, I just don't know if it's diffraction or over processed in that point.
Cool shots either way.
I know what i like, If not always why.

I also really like the first shot. Keep going.

Since the bulk of it (from middle left to bottom right) is all on the same plane and in focus I don't think it is diffraction but simply a mega shallow depth of field resulting from the high magnification. If the point of view were shifted around to the left slightly, or front - however you like to describe it - then the out of focus part will be brought further inside that shallow area of sharp focus.

Getting as many elements into the focal plane as possible is a balancing act that you need to see in real time as you bodily turn the subject in front of the lens. Unfortunately you can't do this readily with a modern AF lens because its aperture remains wide open until you click or stop it down, at which point, Live View shuts off AND you run out of fingers and hands! This is where old glass, such as Takumars, Meyer Optics and the like wins hands down, especially if it's a preset because you can also twist their aperture rings around quite freely and watch the effect happen in front of your eyes.
Both the *istDS and the K5 are incurably addicted to old glass
