I know it is your YT character. Please dont feel offended, I speak only friendly with best intentions. Your character have exactly 10 solid colors, good ammount would be around 50 to 100. Also there is nothing bad in buying assets when you use them in good manner. May be your vision is not regular, I dont know, but check in google what is high contrast mode, that is how I see your art. Again, no offence, best intentions
