My Birthday Presents

So I asked for shelves and I was super excited to get them, but once I got them I was worried they were too big and I had no clue as to what they would look like, so I got some help on what they would look like.
First I looked at the front view...

Then the side view...

Decided they were too wide and I needed skinner shelves, but still the same length, so back they will go and hopefully I can find other ones that will work better.
