Simple wordmark - not the obvious "flowery" design. Dots symbol to hint at both the flower head and the fact you contribute to good cause organisations (dots representing all different entities with you in the centre). Another subtle play is how the double 't' is joined together - like you're close-knit, 'friendship', etc. - all of the values that the word "metta" holds.
I like the concept of the dots, but the colors are a little too dull. I know we said no harsh colors, but can you make the colors a little more lively?
Also, the dots are an interesting concept, but can you take it one step further, create something that can almost be used separately from the wordart as a symbol of our company. Dots are a little too vague. Use the charitable/ eco friendly angle a little more directly.
