Hello 24charlie. I got here through Getty Icons. I really loved your icon designs. They're very beautifully designed and ideal for newer systems, especially when the software designers didn't make icons that match the system.
The only thing that I would personally change is that below 32x32, the text on the icon is barely readable. I think that 24x24 and below should probably not include the text because of that. It would give you a chance to make the images a little bigger too. Just my two cents on your elegant icons.
