Your logos are a unique type of design, so it's rather hard to critique when one does not see much of it. I will do my best, by critiquing what I see in this lone image and what I feel about it, as it is not my expertise in art.

The colours look very well blended, and the texture added on to it really makes it pop. The letters have a lovely fluidity, yet sharpness to them, making it clean and crisp.

I think that the 'A' should be more clearly defined, though. The heart shape that puts the bar in the A is what slightly detracts from it. The 'M' is clearly visible, however, the A sorta looks like and upside down 'V'. That's the only bit I would really fix on this.
The circle design for this logo actually works better than a square or fully deigned piece.
Lovely work!
