Is it a problem with a cemented implant crown to have the shape changed by sanding it down? (Phtoo)

I had a dental implant permanently cemented about a month ago, but now I realize that when I take pictures I notice my implant crown is too long and I would like the outer corner shaved down. I added a picture. I know the color is off as well, but we had that redone 3 times and this was the closest match. It doesn't bother me. The shape does though.
