First of all, passion is the most important factor when it comes to creating art or any other skill. If you have the passion then you only need someone to guide you through all the steps and layers of creating an art piece. I have a philosophy "I can teach anyone how to draw". You can learn drawing if you have someone who knows how to teach it. Talent comes after you have established the basics. So, to answer your question, you can start by hiring a professional tutor who can share their experience with you.
