Well I'm still here - for the moment... will be leaving shortly.
I have flipped back and forth many many times
and have decided the previous one to this (your current entry) is stronger -towards the theme.
Two things in this one... the rider seems out of place here and my vision is pulled from the machine towards the background curve
and lingers in the distance on the far left.
My original thought about the wall was that is was a little distracting as well. but looking at it again now, it lends to give context and reality to the image.
