To give us an idea of the overall feeling of your brand, let us know which styles you lean towards
'Cha' is Mandarin for 'tea'
Prefer the following...
pencil sketch look
two birds featured in logo (can be on a branch, flying, sitting on a letter, etc, up to you)
A tea leaf could be a nice approach to the logo...perhaps bird holding leaf?
Birds can be in form of silhouette - or not- up to you.
Subtle hints of Asian-style can be used in logo. Nothing TOO Asian. (ex. perhaps the birds resting on bamboo)
The above are my ideas - but, I'd also really like to see the imagination and creativity of the artists. A completely different look is open for discussion as well.
