Emulated Photo for Dominique Bollinger

My second person that I emulated was Dominique Bollinger. I think that I got some of the concept in the photo but I don't think that I got everything that he was working for into them. I decided to make these pictures black and white because I knew that Dominique Bollinger used a lot of black and white instead of color. Do you think that the black and white makes the photo hard to figure out what is going on?

Emulated Photos of Matt Siber

One of the artists that I decided to use for my emulated artists was Matt Siber's. One of the things that he would do that I thought had a very unique look to it was his signs that he erases the posts for them and just leaves this floating sign. I did this by just taking some pictures of some signs then in the photo editor I took and erased out the posts for them. I like the one on the left the most because I think that I did a better job at erasing the post then I did on the one on the left. I also think that the one on the left is more successful because the background is lighter so you can really tell that the post for it is actually gone. The one one the right I think doesn't look quite right because the background is dark and it looks like the sign post is just blending in with the background. What do you think that I could do better with these photo's?
