Game UI Beginner Seeking Feedback & Improvement Ideas

Gestalt_I

Hello there, it is my first time designing a Game UI prototype for my personal Project. Problem is, it looks very boring and lifeless, meaning I have room to improve. Being it my first time, I have literally no idea what to pay attention to and how to make it more user friendly. I hope to get a general assessment how I can tackle of ways to improve it. So sorry for not being able to be more specific. Being new to it myself I have no idea what needs work. Thank you very much.
