Oh, lort, okay. The thing with art is, not everyone likes what you like, not everyone in your friends or family is going to jam to the same jam you jam to. It's like music, you can't like everything. Maybe your mom just really does not find your style appealing, and that's okay because she is her own person with her own sense of aesthetics. The good thing is, someone else out there will like your style.
My other point is, do not EVER make art to please others, NEVER EVER EVER do that! That's is a sure way to hate your art and hate yourself. Make art for YOU, because YOU like it, because YOU wanna make it, not because you think it's going to be well-received by others or make you money... that comes later LMAO (lord knows I've sold out by drawing sexy boys). Thing is, people can see your passion, people are really good at calling the bullshit out in art, if they see your passion they will vibe to it. It sounds like a bunch of crap, but it's true! You can always tell who is making art just to make money when you go to conventions, there is always that sense of desperation or something lacking from their work.
Bottom line is, do not go out there trying to please people because you will only hurt yourself when someone isn't pleased with your work. I promise the moment you start doing things for you because you like them THAT will attract you more visibility than doing things to make others happy.
