What style is your art? (And, I have often heard people mistake medium for style.) Granted, I am much better at discussing and recognizing art than actually doing it - maybe my style is verbal/written! HA! But, I truly think that your style is something that develops over time without conscious manipulation on your part.
I also think that "style" is a two part subject.....that is to say, for instance, "The style of the piece was Abstract and her fluid organic style was recognizable from her other work." The first style you learn through study and practice. I think copying the masters is a valid and necessary part of learning about Impressionism, Photorealism, Ab-Ex, etc. The second is the style that your work shows no matter the medium, subject, or style.
I really wish someone had explained this to me in this way a LONNNNNGGGG time ago! I found myself intimidated and immobilized early on by thinking I had to chose (or "have") a specific style to be an artist! Now, I recognize that every person I ever met is an artist in some aspect of their lives. Somewhere, they create an expression of their concept of beauty. I have a friend that is an artist in the kitchen and prepares wonderful dishes that are "things of beauty" to the taste buds. Another is a master of design when it comes to decorating and arranging her house. I have seen workshops that are so aesthetically organized and efficient that they should be framed!
Guess the purpose of my ramble is to say that I believe we all create our own style in our own medium as we go about our lives, and acknowledging or recognizing our "style" is great for self image and confidence. Also, realizing that our style is like everything else in life - ever evolving - is important, as it takes the pressure off!
