It's not harsh at all.
I see shit like this all the time on youtube. You have 13-14 year olds with pirated c4d making shitty youtube intros, and other things like that.
This isn't any different, he's just taking assets and shit and tweaking premade scripts.
Just because it's not the normal thing that a 16 year old does, doesn't mean I should care.
The only thing that should make me care is the level of quality that he produces. And at this stage, it's poor. It's almost the same as those people that post something they "made in like 5 minutes" and expect people to be impressed.
Maybe it is kind of harsh, but he just to keep making shit. Without expecting anything from it.
Age shouldn't be an excuse, or a boon. If you do good work no one will care what age you are. Unless you go parading your age around looking for attention.
