Hello there. Nice to see you eager to show your talents to the community but threads like these aren't allowed. Please refer to the art and design rules for info regarding what kinds of threads are or not allowed. Gonna close this up, sorry.
Edit: Now that I'm not on my phone, I can elaborate - I myself create yt videos and I really love it when it reaches out to as many people as possible. Can definitely understand your desire to get critiques/feedback on the video but this is not the place to do it. A&D rules state that if you intend to show off some of your works, you may post it in the art critique & showcase thread. If the number of works you wish to showcase exceed four in a single medium or eight in more than one medium, you may post a gallery. Now this video here is something I can definitely see going into the art critique and showcase thread but...but the way your post has been worded it seems as if your sole intention was advertisement. And advertisement of any of a user's external account be it on youtube, deviantart, tumblr etc. is not allowed here.
BUT I think you can do this - I can see you're fairly good at art. Why not just take four-five pictures of your drawings and post a gallery? You may as well post your videos in there. I've been doing something similar for a while. Though you're only allowed to post videos if they're not the primary 'focus' of your gallery. Like, you may post four-five drawings and throw in a video doing a speed-sketch of one of those along with the other updates in the thread. Definitely don't see anything wrong with that. So yes, in short, as long as you don't flood your thread with videos and ask other people to like/subscribe, you can definitely go ahead and create a gallery.
