Kat Sloma recently featured my photo "The Crossing Guard" on her website The KatEye View. You can see it here.
While you are there, take a look around at her own amazing images. Actively participating in online photo communities is a great way to expose yourself to other artists and to learn from them. The key word here is "Actively". You need to comment on other's work, click on links to their blogs, accept their criticisms. The end result will be an amazing improvement of your work and an expansion for your appreciation of photography.
