If you're making a customer wait months and months for something they paid for, that should be called out.
Excuses exist, but as soon as you accept payment for a service, art stops being you hobby and becomes a job that requires a level of professionalism.
Why can't the people I commission just do the fucking art I'm so sick of waiting months and months and months for commissions. It's Infuriating as much as it is disappointing because some of them I looked forward to commissioning again but after this wait, NEVER again
