1. The gorilla should look a) strong and b) friendly. We are selling products that are strong and made of high-quality material.
2. Would prefer the gorilla to be front-facing. Would prefer to see the gorilla's upper body only or face/head only. You can make a full-bodied gorilla if you feel it is relevant to your concept.
3. Need a very strong visual identity so that we can get a high level of brand recall
4. It would help if the logo would look great in black & white as well!
