Logo design is for me very occasional work, but I thought I'd share a few examples in one place.
I love simple, minimal logos, although some of the above examples don't adhere to this because obviously the client has wanted a more detailed image. This can be a challenge but satisfying when the little elements fit together in a pleasing way. I think an illustrated logo can add an extra little bit of individuality and friendliness compared to more slick, corporate, vector-style logos (that are best left to a graphic designer), especially with the hand drawn imperfections.
