It looks good to me.

But for future reference, don't use a tape measure. Use a wood or metal ruler.

If you don't have one long enough, you can even glue some balsa sticks together to get something long enough and just mark it where it meets the elevator - after all, it doesn't matter how many inches it is, all that matters is that the two measurements are equal.

And DON'T use string! It varies too much.

As far as a next kit, a 4*, Tiger II or Great Planes Rapture would be a great choice.
