Minimalist Symbol Logo Design

I am looking for a clean, minimalist logo built around a single, memorable symbol rather than text. While I am open to abstract, geometric or even subtle animal-inspired marks, what matters most is that the symbol feels remarkable and instantly recognizable at any size.

Here’s what I will need from you:
• Three distinct concept sketches exploring different symbolic directions.
• One refined design based on my chosen concept, delivered in vector format (AI, EPS, SVG) plus web-ready PNG and JPG.
• A simple black-and-white version and a full-colour version.
• A short note on colour values and typography suggestions (in case I decide to add wording later).

Please share a concise portfolio of logo symbols you have crafted in a minimalist style so I can quickly gauge fit.
