did you modify the lens on the Holga (yourself)?
i recently started doing the lomo pictures, i thought it looked great and its very accessible ($). still hard to get good pictures though. you got some good ones for sure. Im not really into the concept of lomography, though. Going through a shopping mall and just snapping away doesnt do it for me.
The last one could be an Emerica ad if you had Spanky in there holding a plastic bag.
