Indeed it does, nice work. The planet is a very interesting background and has a cool color scheme. Can I make a suggestion. I like the button colors, but it might look really nice to have the colors match the color temperature of the background (which it mostly does already). So cool colors (blues, greens, purples) on the right and warm colors (reds, yellows, oranges) on the left. The Quit button as purple might be better served as a neutral color like grey or off white.
Now that you've done the tutorial, try designing new buttons, or move them around to get experience making the mainhall mask.
Good work.
