I mainly go to Webneel.com when I need some good freebies. It’s a blog website mainly for graphic inspiration but they have a lot of good resources too. I come across some good quality typefaces and icon sets on here.
You can also find some Photoshop and Illustrator tutorials, and free downloads for brushes, layer styles, vector illustrations, and so on. They provide a lot of examples of work to get you thinking about your next project for things such as logo designs, website designs, and type treatments.
Besides being a good source for designers, the blog is also geared towards other fine art professionals such as illustrators and 3D animators, so you’ll find a lot of artsy imagery on here too.
