You're just doing coloring experimentation.... You just got to get out of this slump and continue on! Color has no definite term or way... You are a creative person and so determined to follow your dreams! Don't feel down on yourself! Believe in me who believes in you!
But your colors are so beautiful and amazing! I like all the bright neons and colors! And I think all your drawings are awesome, too! But if coloring's starting to feel like a chore, maybe you could take a break or something? Instead of working too hard and then being unsatisfied~
sorry, I's terrible at giving advice. Just... Keep working and you'll get even better! Yeah!
I love your art, and I think your colors are amazing~ <3 but If you feel like its not something you enjoy doing at the moment than take a break and try some new things, maybe you will find new , more fun ways to do art, dont force your self into something that you dont like doing, it will only make you hate your art.
