That's literally the artist's perspective, Even mine, But generally it's a normal thing to view your art as bad, But using that for improvement will make a major change to your art, And how you make or process it, But something that you may add that may take you more time is, Clothing folds, Shadows, Basic human anatomy practice, Generally practicing will increase the SPICINESS in your art and others, But I can assure you, Your art is indeed one of a kind to be seen. Which doesn't mean a bad thing but a good thing.
