Putting a filter over a photo you found in the internet so it looks like a shitty polaroid isn't art. Neither is resizing or cropping an image, or adding text to it. Recoloring existing characters and calling them original isn't art, it's plagiarism. If that's all you can do, then you are creatively bankrupt. If all you can do is take existing characters and make them "better" then you are creatively bankrupt. A child scribbling with crayons has more creativity than you.
