My attempt at doing Lomography in Photoshop

Here are some Lomo shots that I have been playing around with in Photoshop. They are all taken with my Nikon DSLR, but I wanted to see if I could make it look like they were taken on a Holga or a Diana or any other Lomography camera. If you would like to, please let me know what you think.

To start things off, here is a "polaroid" 

Here is a first attempt at a "fish eye"

Here is my first attempt at a Lomo or Holga-type shot

Here are some more attempts, this time with "light leaks"

But, most people shoot in 120 film when they use their Holga, so I decided to try making this last shot square, and do some different types of "light leaks"

Here are a few more examples

What do you guys think of this? I would love input as I am always trying to improve on both my photo taking as well as my composition and post-processing.
