I get my inspiration from my feelings. My inspiration really relys on my feelings..Fear..Sadness..Anger..Happy..etc. If you feel angry or happy, use your imagination and think of some things you might want to throw out onto your computer canvas on photoshop or through camera or through paper. When i do. I Feel great.
But whenever i get a block, i decide to storm out of my house and take a walk and look around me. When i look at how beautiful nature is. then my feelings feel inspiried to make something artistic. So thats another way that helps me get inspiried.
