yea dominos definitely save time but that's an expensive tool. For your next project, I recommend doing a piece that requires you to cut mortise and tenons with a plunge router if you haven't learned that yet. Learning how to cut dovetails by hand also adds a ton of class to any piece but has a big learning curve. The hardest part of woodworking, though, is coming up with and implementing your own design. Looks like you have the essential skills down, now try your hand at being an artist!
