You bumped after three hours?
My, I waited three DAYS before I bumped, and still don't get those many replies ... sometimes the photos we think are brilliant are SOOO boring to othersthat we should revise our opinions over our own work just by the LACK of response...
But you will be lucky and get more response than I can ever hope for, since the last two have been pp-ed to an extent that many will tell you they have serious issues, though you might have PLANNED to posterise them in the way you did ... only - it doesn't really work for either of the two.
Exposurewise, assuming you meant to expose the the light bulb as such, the first is ok, by you might go look for a more interesting light fixture next time...
The second is too centred and may be interesting, but not in the way you are presenting it here. It looks pale and flat, and you might have used the pp you used to overcome the overexposure. I don't know.
The last is primarily pavement with the saturation of red and yellow cranked up to extremes, then people who do whatever it might be they're doing, queuing in line for entrance into a club, maybe, and the blues are too saturated there, too... Hmmmm. Not my kind of image...
