This happens to me too. As much as I hate to walk away from the studio and force myself into the yard or paint a bath room, clean the house, it works. I spent two days in my yard, mowing trimming demolishing and weeding until I could sleep good. Then I went back to the studio. Good food, good sleep and some sort of exercise will usually break the block. But...YOU must force yourself away!
I have phases where i love art and i work very hard at it and in the end i have a great piece of art. But I have no inspiration right now and i really want to create a new piece. I love to paint nature and i really want to get better. Any inspirational scenes that i could paint or just anything to get my creative juices flowing?
