If you have more than one photo of the same then yes best just to put them all on same page. After you upload the first photo just clear the IMG Code box, then hit Upload again. Allow a space between each photo.
Not sure why the house is tilted left but it's a little distracting to me also the big tree. If I was to have shot this I would have left the tree out of the photo then I would have crop the right side how ever much to balance out the photo but that's just me. The photo looks a little flat to me and could use more punch. Here it is again if you don't mind after I when over it in LR.
