Keep in mind, doing drywall well the first or even tenth time is going to end in disappointment if your expectations are even remotely high. Mudding drywall is an art. You can learn the basics watching videos, but you'll only get better through loads of practice.

I also wouldn't recommend having started your first time with hotmud for anything other than filling large gaps. It's not nearly as forgiving as pre-mix taping, all-purpose or topping mud. It's also way harder to scrape or sand.
