Stop worrying about whether what you're doing is artistic or not, whether you're being creative enough or not. Whether what you're doing in your art journal is good enough. Whether it's wrong to change something in landscape or photo. Whether it's okay or not to use unrealistic colors. And stop worrying what people might say.
Get yourself an artistic license and the next time someone says "What is it meant to be?", you can say "It's not meant to be anything, it's art, and there's my license to be artistic hanging on the wall."
