Not at all.
It may be stating their opinion, but it's also unnecessary bitching by a bunch of kids. Where the people complaining about them at least understand that bitching about the prices of someone's art is really stupid and unneeded.
I'll probably go ahead and just disable comments soon because DA gives kids a false sense of both entitlement and worth of art.
This is just lineart, it's not a necessity, so they don't HAVE to buy it like I've said a million times by now. owo
