When being criticized, the words that hurt the most are from family members and close friends. We expect them to be more encouraging and assist us. The thing is, the people who love us have been around us for so long that they can only see what we can do in the natural light, unaware that we have so much more on the inside. Best thing to say to them is "I know you love me and want to say advice to assist me in life, but please understand I have to follow what's in my heart. The dream is in me, not you and I have to do what I feel is right".
you should talk to your mother, show her your art. You're pretty good! THo it's a hard world and not easy to find a job.. Maybe you can do a bigger thing, not ONLY illustration. I do animation, editing, and visuel stuff for school. So I can do a lot, but I'm not a ''pro'' in everthing, I just know a bit more then the basics You can also try to draw MORE things, so your package will be a lot bigger! and you have more to show
If you have any passion in medicine at all, I'd say pursue both. Art is my passion, but veterinary medicine is what I want to DO and make a living with. I plan on getting a double-bachelors ( also called a "joint-bachelors" ) of fine art AND science, and then begin apply to art-related jobs to pay my way through medical school, that way I have a healthy balance of both. If you have NO passion in medicine, forget about it! One day your mother will be dead and you'll be asking yourself, "Well... now what do I do?"
Tell your mother sternly that you love her and respect her opinions, but she won't be there to dictate your life forever. You NEED to do what makes you HAPPY. She may "disown" you, but more often than not, given time, the gaps WILL be bridged. Just have patience, and don't give up on HER. If she doesn't want to hear from you, still send her birthday presents, perhaps via mail. That will let her know that you're still thinking of her, and you still love her regardless of what she's said or done to you, and it will FORCE her to accept you as you are. It may take years or even decades, but I would be willing to bet that she will eventually come around.
Besides, with only the briefest of glances I took at your gallery, I can tell you have a real skill at landscape design and your painting is beautiful. You will be highly sought after in the art world once you become well-known.
Then I think everyone would be better off if you weren't a doctor. There is nothing more deadly than a doctor who hates his / her career.
If you continue to follow your passion with painting, I feel that you will find a great deal of satisfaction in it. Follow your dreams, MAKE them come true. You have enough talent to go incredibly far.
