Because everyone starts somewhere. I made ms paint comics with comic sans when I was really little. Did I post them online? I honestly don't remember. If I did, they're floating in the dead husk that is neopets. Anyway, were they any good? No. Of course not. You have to learn to suck really bad before you're good at anything.
My first 3D models I made were terrible. I couldn't pose or rig things properly, but I was proud I could even do them at the time.
I think we all have had a time that we drew something and were so proud of it. Looking back, you probably cringe even laying eyes on it now. These CGI comics are no different. Give the creator some time. They might one day amaze you.
