making designs for my sister

So my sister asked me ( since im Graphic Design Degree ) to create a logo for her band section. She plays the euphonium which is something I learned. Anyways I hopped onto my program and created the logo for her. Basing it off of whoever designed the logo before ( they were attempting to create one ).

I edited aspects of their design and threw my logo onto some shorts for a mockup. I did not remove the background fully because it was a quick mockup for her.

I don’t know if she’s gonna use my design, but it’s good practice.
