who’s line?

I’ve been inspired by watching a full on marathon of the legendary Who’s line is it anyway so I started off with 1 line in illustrator and created an abstract heart shape as I went along. I think it captures the ‘improvised’ style of the show with the suggested movement with the linear design, I decided to fill it in red and think it almost looks a little iconic…?…it seems a bit familiar but I can’t think why? Any ideas?
