Very nice images. However, i feel the shallow DOF is overdone in the first image ... seems to have turned into an abstract. Took me a more than a few seconds to figure out what the image was about.
Cheers ... J.R.
Thank you for the feedback

The photo was made with a flipped lens, so I didn't have control over aperture. That's why I bought an extension tube recently to cover this type of shots

Though I feel that the image is special due to its extraordinarity. Anyway, I'll take into account what you said and will probably replace the photo with something more interesting
