Getting criticism is difficult. I think that what you got here was ok. Not sugar-coated but that is understandable and also proof it is honest.
You may also want to understand the context. Here in the Forum we get ~10 people doing the tell me how to be an instillionaire with my garbage gig a day. That takes its toll on the subtleties as there is nothing subtle about it, or honorable.
I think the others are right. Mostly. So I am going to try to not be too blunt - even tho it is my nature. I am a Mix Engineer & Composer. I work on films, I work with my 9 yo who wants to draw and make films.
Commenting on the Colorist gig, this is probably confusing as who needs things colored in? Still, give it a go. The drawings are in a Naive style (yes a term). I am rather a fan of that when done with a great heart as it can cut straight through in ways that “high” art can miss. Your work has some charm. What it lacks here is a strong sense of purpose that eclipses the technical skill.
What did you study at college? If it wasn’t Art, you might not want to mention it as putting it there casts the assumption that you studied art. if you didn’t study art then it raises the Q: Why isn’t this person selling what they are really trained for? people are harsh when it comes to spending $5.
In your FAQ, you list a lot that you won’t do. Your call but some seems a little narrow, this limits you greatly. Many people buying here will be after elves, dragons, ocs, nasty little Hobbitses, and whatever else is in their hack n slash games. You don’t have to do that but if you can’t show a strong lead and close off other doors…
