The design process is incomplete without creating all the assets for the project yourself. I do not consider myself to be an icon design but I do a pretty decent job at it. Below are a few of my icons designed at x and 2x sizes as well as for different states like default, hover, active etc. I have also experimented with responsive and interactive icons.
Icon design, Metaphors, Retina, Responsive, Symbols
Icons designed for various products
The below video was created to demonstrate some of my explorations with responsive and interactive icons. The idea was to animate SVG icons at different states.
