Ekke needed a new t-shirt design and created a contest on 99designs.
2 winners were selected from 66 designs submitted by 22 freelance designers.
Not sure. Might be "retro" (e.g. "University" or "Apollon Space Misson"), or just "cool", or "fun"... but not too female, not too fine-lined and fragile, but also not "computer arts / rendering".
Oh, and taking a well-known brand logo or style (like "Coca Cola" - just an example, please do NOT use this!) and "interpreting" it might also be an idea.
No photos or additional illustrations please: The icon should be central!
The logo (including the full "Leuchtfeuer.com" and "Digital Marketing") should appear either as-is, or maybe manipulated / stylized.
Some words may also be added if it helps the design (e.g. "Est'd 2018", or even a bit longer), feel free to work with generic examples and we'll be creative to come up with good content.
