This is super fun!

One small thing which would be nice is the ability to just download the sqlite database myself so I could use my preferred application to query it, and just use the site for the brief, notes and submission.

Also a nitpick, while you say it's for "learning" SQL, I would probably expect something a little more guided, or at least some example queries, if the intention was to teach SQL. As it stands, if you don't know SQL you're probably going be completely lost as to what you should be doing. It's really cool, just not specifically as a learning tool.
