For you demo reel you should look at it from the perspective of an employer. Ask yourself, if I were employing me, would I do so on this work/reel? And be honest. Also remember that your reel is only as good as the ‘worst’ piece on it.

I think that many people, including me (well, not as much now) are too scared to re start a project as they’ve put so much effort into it. They may know it’s not up to scratch, but are unwilling to accept it, and try to simply work around it, when in fact it’s the foundation of the work that incorrect so no polishing will improve it significantly.

If you did the same project 5 times, compare the first with the fifth. There WILL be an improvement. It’s almost a guarantee.

Basically don’t get too attached to your work, especially as your learning. You find it easier to take criticism, and easier to scrap it and restart if it goes way of course.
