People say art comes naturally. I say it starts off with an interest, practice, then failure, then practice, then a little success, then practice,...... you get the picture. Artist is always learning, it is part of the beauty of being an artist. You will (By your own opinion) always have more failures than successes. Always keep old work or a copy of it in some way. A year or two down the road pull it out and look at it and compare it with what you are doing at the time.
You will have a wow moment.
Keep up the work, don't let anything get you down.
