to new artists: dont ever be afraid to borrow inspiration from concepts you like. no matter what the people on this hellsite tell you, its not worth the artistic paralysis that comes with worrying about people dogging you because you have a similar character design or composition.
art is becoming more and more widespread as the industry expands, people are able to teach themselves how to do it without ever taking classes. classic artists often learned under mentors and collaborated using their name in secret, thats a thing of the past because thanks to todays technology everyone has access to this information.
part of of learning the trade is taking apart successful artist's process and knowing how to recreate them! you might feel guilty at first, but it will stop feeling like copying as you begin to mix more influences. i wish i had discovered this at a younger age, but unfortunately the toxic mindset of communities like this one prevented me from realizing it sooner.
just remember to be respectful, cite your influences if you took heavily from a concept, and dont attempt to monetize from work done in your studies without the original artist or photographers consent.
