Question about teeth as well as lower jaw/maxilla position. (photos)

I just got a copy of my dental x-ray from my orthodontist. He stated that he would be able to straighten the teeth without any removal or need for IPR, but why do my teeth seem to be in a curved pattern as opposed to many others? My x-ray is on the left and another on the right which seem very well aligned. Is my palate too small or is my lower jaw/maxilla out of position judging from the frontal view? Is there anything that could solve this
