Not sure if this criticism is constructive or not, but, a couple of thoughts on the pizza icon part of the logo:
- The ones with one segment partially removed combined with the color of it, reminds me of PAC-MAN.
- It's also vaguely reminiscent of a slice of orange or lemon, again probably because of the segmentation and color.
- Is it pizza or the stone? Both or neither? The segments, especially with one removed suggest it's pizza but the color and the product name suggest it's a stone, except a stone shouldn't have a piece removed. So I guess I'm kind of confused by it.
Just some thoughts, feel free to disregard! I'm impressed by your product and efforts!
