Great story! You do need to work on word usage (there vs.their, etc.) and you have some run-on sentences. Find an editor to help out. You could have slowed down a bit, and drawn things out, but you have a good sense of the Doctor and his personalities. Keep working on this story, and I'm sure that you will come up with more ideas to work with.
All in all, a great start. Keep writing! You have talent.
