2 years ago, I submitted a movie called "death of the yellow" At the time, my only exposure to uploading things on the web was short 3 second videos like that, and I didn't realize that NG was a site meant for quality. This BLAM was the wake-up call that I needed in order to get motivated to make high effort cartoons, and it's for the better!
I don't consistently upload movies as it takes forever because that's just the process of animation, but it's rewarding to put something out and see it get a good rating.
I can see why getting blammed would be something that discourages people from making movies, but it shouldn't. If somebody points out criticism that can be proven, like anatomy's bad, or the pacing's bad, or anything like that, maybe it'd help to listen.
I'm not sure where I was going with this, and maybe I shouldn't be talking since my Blams severely outnumber my saves, but I do know one thing.
Keep making stuff, see what sticks!
