Interesting

Well notbad with this logo of sorts if you look closely you can see the fine detail. I for one wouldn't mind more deeper color more texture in the reds and blues it will really make it pop out at you maybe even adding some borders to this along the edges would be a huge plus of ideas but anyways nice work on this piece here

Some deeper colors and some borders on edges

Pretty nice logo. I like the strength of color, and the subtle Yin/Yang like contract of it all, though that particular combo makes overall shape remind a bit much of Pepsi. Would be cool with a larger resolution though, even if this is the size you plan to use it's a bit small as a standalone piece.

A nice logo design.

My advice would be that if your going to upload a logo to the Art Portal you should consider creating a complete style sheet, by that I mean: the logo in different sizes, a logo with text, a business card design, in greyscale etc. This will showcase your design and it's versatility.

Other than that the logo itself is a simple and effective design.

Keep it up
