Yes that is not bad, you can figure out how long each frame takes. Your image is fairly simple, so I don't expect it to be so long, but actually ~7 seconds per frame (my rough calculation) is pretty fast. If I was working on a short animation project, I would probably try to get my renders below 5 min per frame, which would take 83 hours for "only" 1000 frames. But different projects obviously have different requirements. I heard that rendering Treebeard for Lord of the Rings took around 48 hours for a single frame. Obviously they used many many computer to get the job done, but you see what I mean.
