Good for you for putting yourself out there. I realize that short video probably encompassed about an hour or more of shooting and even more time editing.
There are tons of videos of guys just shooting, heck I have several myself. Be different.
It can be rough and take more time than shooting but tell the viewer what you think. What do you like? What don't you like? Are you planning on adding something?
Finally watch some other YouTube videos to get an idea of what is out there. Range Time with Cory and Erika is a great one as well as Hickok45.
Again good job for putting yourself out there. Keep it up and who knows what could happen
