Turning a Closet into Bookshelves

I have been planning this project for a while, but we just have not made the time to do it. We went to work yesterday on it and I was so excited. I measured the closet to get my shelves evenly spaced out. I wanted to have four shelves to fully use the height of the closet. We started with the top shelf putting in the brackets and making sure it was all level. Then we put the shelf on.

So now I need to decide to cut the shelf and make it more shallow. To cut the shelf in half from front to back and make a shelf on each side. Or to lower the shelf and just have three shelves. So we stopped for the night last night. Putting that shelf up took almost an hour. I don't know if you can see but there are already some holes in the wall. If we decide to lower the shelf I'm going to go back and fill in the holes and possibly give a coat of paint.
