Photoshop Panoramic

I received a DSLR Nikon camera for Christmas and decided to purchase Adobe Photoshop along with it. I have been watching videos and trying to teach myself how to use it. On a recent trip to Disney World I took a few pictures of a painting on the wall so I could try and photoshop the picture together into 1 panoramic, below is what I came up with. I also used the free transform to fix the perspective as much as possible. It has some lighting issues but that will come with practice. Let me know what you think, it was originally 4 images!
