It’s a basic design I feel like the options placed onto the screen looks quite fine but simplistic. However, there are many things you could do to make it eye catching. This depends if your wanting a simplistic design without properly detailed areas.
If you look at other games that feature similar approaches as yours, you will see most of existing games features scenes of what the game is about it’s basically providing users on what there expected to see or what it is going to look like. You could incorporate a similar color pallet design for each button and text.
You could even add a outline around the text so when players navigate to the UI a outline will show up. I’ll attach a image below to give you a general idea. Other than that everything looks fine already some improvements can be made if ever needed in your case!
