Absolutely leave it in. You would lose any reference to scale and context with it gone. Just like many others above have said. I might have considered purposely adding vignettes or other artifices to point towards the subject in an otherwise blown background? I am not a fan of the "significantly overexposed" effect (blown out to be more blunt about it), but then that's just me.
The shadow totally grounds this! Love it!! I haven't figured out what you're doing yet (LOL!), but it's looking great through my eyes!! Is this the minimalist approach? :)
@tctime tx TC... not sure what you'd call it... i just kinda like what happens sometimes when overexposing... and then i feel a need to exaggerate it into surreality ;p
