I’d like to share the Pxleyes website (“For Pixel Addicts”) with you, a graphics community site that invites you to participate in Photoshop/Photography/3D contests. It helped me a lot when I was first learning Photoshop by giving me the motivation to create something and share it with the Pxleyes community. Your uploads are posted on the contest wall and other artists critque your work.
Seeing what others have created, starting with the same picture, is very inspirational. Most artists upload step by step guides of their work as well. Going through these step by step guides, acts like a tutorial to help you learn new techniques.
Pxleyes also has a magazine, called The Eye, which you can view onliine or download – check it out!
