|Greetings from the Critique Club.
Wow, I love this! I'm surprised it didn't score 6+.
Technical stuff: the image is nice and clear, the B&W works extremely well (it really brings out the illustrations on the guitar, and subdues the background which might otherwise be distracting). The DOF is perfect.
I think the POV is what really pulls this picture off for me. It seems to bring the guitar to life - I can almost see it stretching, glancing at the sky, then carrying on with its stroll around town... The empty space to the right reinforces the impression that the guitar is out for a stroll.
No idea what post-processing you did, but it worked well anyway - the image is interesting, without being overprocessed.
Anyway, well done, I love the picture.
Any questions, just PM me.
