Here is a small group of icons that I'm currently developing for a software client. Although I've created hundreds of icons in my days as a designer, I've never really done a full fledged icon set for a client. The client gave us the choice to either just purchase a series of icons that would work with their existing site design, or create them from scratch. Instead of rushing to open a new tab in istock, I opted to push some pixels around, get my fingers dirty, and do them myself.
Note: I typically do this for any artwork, I never buy stock web graphics, EVER.
As you can see they all follow a similar look and feel; the reflections, the gradients, the rounded corners, color palette, etc.* They match the aesthetic of the dark themed website quite well. Of course I also made sure to fit all graphics to the grid and have pixel perfect lines whenever possible. What do you think?
*(Disclaimer: I don't condone excessive use of reflections, the web 2.0 look, etc., I was just following the preexisting site design haha.)
