To me, #5 stands out from the others as "fine art" and something to study. Tonal values, lines, scale, composition, subject inter-relationship, pattern, etc. While they are all excellent ... many of the others have a "cool" factor that might suggest computer theatrics moreover than "fine art" for some audiences (not us of course) even though that isn't the case.
The only downside to #5 is your desire for it to be signature "YOU" ... but as an attention getter/introduction to "YOU" for THAT audience, it might be a play to consider. To me, #5 has the most "classic" vibe going ... whereas many of your others have a much more "contemporary" vibe. Still all excellent, but I really dig the excellence of #5 ... many of the others are initially more "compelling", "intriguing" and "curious", but as a "fine art" study #5 holds me longer/stronger than the others.
Here's how I see #5
+1 @ WOW / Excellent
+1 @ Fine Art
+1 @ Educated Mind
- 0.5 @ Signature You
#9 shares some of the strong "fine art" elements (tonal values, etc.) but has a more contemporary vibe due to the inclusion of the crystal ... but the crystal says "computer", imo.
#8 that I mentioned before as being what I consider "iconic" YOU ... has that "cool" factor to it like so many of your images ... but it doesn't suggest "computer" as strongly as some do. It has a pretty good blend of that WOW & YOU & elements to study.
#12 ... defintely an attention grabber, but I leave it sooner than the likes of the others. It seems to be a quicker study for me than the others, but certainly leaves many audiences wondering how you achieved it.
They are all excellent and far superior to my efforts. With a little more info given @ audience, #5, #8 & #12 ... for very different reasons ... are about as far as I can cull it down.
Classic/Timeless ... #5
Contemporary/Outside The Box ... #12
You/Old & Abandoned ... #8
