Best work thus far

I took this photo of an artist in Chicago.  I used a point and shoot camera.  I think it is a good photo because it is interesting and shows an artist at work.

I do not remember what kind of camera I used for this photo.  I took this picture of a friend at a party.  I think it is a good picture because it captures an interesting look on his face.

I took the following pictures using a nikon d3100:

I like this photo because of its simplicity.  I like the lock and the chains around the fence. 

I like this picture because of the quality and focus on the flower.

 I think this picture is good because of the expression on the squirrel's face.  I also like the way his tail is expressing his emotion.

For this course, I will be using a nikon d3100.  I don't know much about this camera, but I am looking forward to learning.
