Some people might be sleeping on this, but let me share a quick process to make awesome, and quick, illustration-style VECTOR logos!
1st, use this prompt on Midjourney:
a logo of a zombified black and green bear's head, designed in esports illustration style --v 5
Convert the image to vector with vectorize.ai and then remove the background and details such as the white dots around the logo with Illustrator or Inkscape (a free alternative).
And boom, an amazing mascot logo for my esports or sports team, or a logo for a client.
