I came across a person here on this site who complained on why he/she get low ratings on his/her artwork, but I'd say fuck ratings, because at the end of the day, they're all based on personal opinions. I've seen artwork that's worse than mine, yet they get higher ratings than me, which is absurd, but that's just the way it is here on this site. Just keep doing what you love to do and not worry about what people think. I made a nude artwork of a copywritten character that I thought was bad in quality, but yet it still has a good rating, not because the art is good, but because it's a copywritten character. It's also good to strive to improve and practice so that you can look back at your old artwork and learn the flaws you made before. I've been looking over some artwork at portal and to me, it seems like if you have 100+ followers, you're more likely have high ratings anyway whether the artwork is appealing, or not.

You see the bullshit?.....But yeah, this is why people shouldn't worry about ratings, but instead, worry about improving
