While performing a UX evaluation for Dallas Pets Alive! I also had the opportunity to make contributions of a few design assets.
After creating the initial set of icons and experimenting with different colors I decided on the set that was all green. Using a single color and reducing the opacity to 70% made the icons not too over powering for the profile pages.
I then returned to the concepts for Age and Energy level. While a sand timer and battery are good indicators for age and energy level, I was concerned about the negative association of having a low battery as well as not enough time. As a solution, I decided to create an icon scale using a paw design.
I also created a wire frame for the redesigning of Dallas Pets Alive!'s animal listing and profile pages, click the link to check it out.
