Like the concept with the hands and use of simple lines. Zombie looks more like a clown/monkey/homer Simpson. Need to have more spirit of a Zombie. A person who has turned into a zombie 40% possible less comical. Right hand (lower) thumb is not accurate and doesnt look good. Font OK. Circle OK.
Overall your concept of the round logo works. We are ok with the font and layout of the circle. The main challenge is the mascot, its not what we are looking for. The Skull and wings are to harley davidson. We are looking for zombie. 50% human 50% zombie. Look online for zombie illustrations to get an idea and then se if you can mold it into your overall logo concept.
