Since I dont use flickr anymore and when I did, I didnt tag my stuff so nobody could find them. But my most favorited one on deviantart is this one...
It has nearly 14,000 views, 964 favorites, and 155 comments. Deviantart has a hell of a lot less users than flickr though.
Most views is this one...
17,600 views, I dont think its even close to my best photo but people seem to love it.
Dude, Giallo, that photo of Shanghai is absolutely kick freakin ass.
