I got all the gaps filled and cleaned up the excess.
That’s not looking too bad. The parts are misaligned, but after painting it probably will only be noticeable if you look closely, so no big deal.

As you can probably tell I am a novice and this is my first model.
You’re not doing badly, by the looks of it. You’re filling gaps, for one thing

The glue on the back piece dried before I could make final adjustment.
The best way to install large pieces like this, in my experience, is to first of all keep dry-fitting and adjusting them until they fit as well as you can make them. Don’t be afraid to scrape or file material away if you notice parts rubbing together in one area so that gaps result in another. (Cutting with a knife is not recommended, because it’s too easy to remove more than you wanted to.)
You can keep unwieldy parts, like (I suppose) hull halves of a boat, together with some sticky tape until you’re ready to glue.
Next, glue only one side into place, preferably the one that fits best, and make sure it stays where it should with some more tape, clamps, and/or rubber bands (whatever works best on that particular model). Then you can make sure the other sides fit and glue them down as well, again adding tape etc. as needed to keep everything lined up.
Also: use thin cement, the kind that comes in a bottle and is applied with a brush. Cement from a tube has its uses, but for parts like these you’re much better off if you can let the glue flow into the join between the parts, because this gives you the opportunity to fit them together first (again, with tape, rubber bands, and/or clamps) and only add the glue when the parts are properly aligned.
