Comments? Suggestions?

I like sepia, but the last would have more impact in b & w.

All of these pics are untouched. They were taken that way (camera settings). I may change the last one on photoshop, we'll see how it turns out.

Very very nice. I especially liked the first one. But I think you have to know the history to appreciate it.

i also like the first one - very original

1st jiggle the hue/saturation or try grayscale and adjust.

2nd=me like!
Obv. stregthen the etched graffiti etc.
Might try the whats-it-called- filter..solarize? (Sry, haven't used Pshop in months..)

Last needs some 'levels' (no, I'm not using the 'curves' word but you know what I mean..ahem [that was for the guys where I know there was a retort-in-the-making..]) adjustment..darker for edges etc. If it were clearer, a cool, close-crop would do well.
