Help with a design

Hi guys, I am extremely new to graphic designing and I am just testing out a few new designs and I’ve chosen one I like a lot but I feel like it needs some more spice, what is something I can do to make it better or more interesting? Maybe a background of some sort?!Buddyexcrete-removebg-preview

I just did a Google search on graphic design and came up with the following definition, which largely matches my own.

What are you trying to communicate with what you’ve created? Is there a purpose to it or are you mostly just experimenting with Photoshop?
