The intro is definitely not too long. Some people may think otherwise (maybe attention span?) but I like fairly long intros. 20 Seconds max, if you have a 30 second intro however, I will mistake it as a commercial lol. I like the newer video.
That's a milestone. You will enjoy it once everything take off Good luck!300 subs would be amazing! I'd be stoked with that. Definitely will continue working as hard as I can.
Who knows? in the near future people may look to you for papercraft wisdom. Keep up the great work. Every will come to light at the end of what seems to be a long tunnel for nowJust making more videos. I'm not asking for anything but I do enjoy other people making papercraft model as myself. The papercraft community has been a bit dead since 2009. But I seen a growth of papercrafters making model that I post on my channel and other websites as well. And a huge thanks for the support to push me to make more and bigger papercrafts <3
