Yep, I can see a younger Steven Tyler here and he certainly has the stance and body type...good shot and observation on your part...we are in for rain here for the next few days so it will be awhile before I get out for some new shots but meanwhile will dig into some old stuff to see what I can come up with of interest to you re: people &/or street scenes and maybe some look-alikes as well.
Ooh yes, I didn't think about the Jack Sparrow aspect, but you're right! The only thing I wish I had in this pose was his croc skin cowboy boots...they really completed the image! :) I've another pic that shows them, but the composition isn't as good IMO.
