dunno if you will like this or not but this is the way i prefer the b/w. i took your color version and converted it to b/w in channel mixer. settings i used: red 40; green 31; blue 33. i also liked it with the red channel bumped down to 35 but since you were going for a more overexposed look... anyway, i didn't have nerves to do the selective color thing. i'm still too sleepy and have to start getting ready for work in a few minutes. anyway...just my 2 cents. :)
