Sleep Walking in HDR!

Thank you for taking the time to view this work. I shot this at around 4.30am this morning, unable to sleep, so 10 minute drive down the road to here. Three shots bracketed one stop apart, merged together in Photomatrix Pro 4 then tweaked in Nik color efex 3. I am not well versed in hdr work, so its all trial and error to me, so forgive any errors and if you have time I would appreciate your shared wisdom on how to approach the subject.

thanks again

Simon
