I always think it is so interesting how the subconscious mind will reveal itself through ones creativity. I find what tends to flow out from me will sometimes emulate those artists whose work I have always admired. Although this is not a deliberate attempt to copy, I find that some of my work will in ways resemble or at least have the same feeling as some of the masters that I have been able to see in museums around the world. It might be a color scheme or even just vibe that is coming from the painting that will spark a memory of something else I have seen.
If you are an artist, take a look at your work and see where your subconscious created an evocation of other paintings you love. Perhaps we are somehow all connected in the spirit of creativity that inhabits every artist and art lover.
