the pentagons... I have a lens that produces points of light that look like a christmas tree after dark (Nikon AI-S 50 f1.2)... I hear you.
That first image is worthy of printing and I particularly like the highlights in the eye (and on the glasses). BTW, are the reflections also pentagons when enlarged? BTW2, it doesn't matter, its a wonderful image
I also like the way you made the enlargement 1:1... and in both images you filled the square very nicely...
