This is weird. I generally don't miss threads like I did this time. :(
Anyway, yeah, dbp's right. We do not allow thread creation unless you have at least four examples of your works. And galleries which are exclusively meant to promote youtube channels are definitely a no. So yeah, sorry but I'll have to close this. You can post these videos in this thread, though.
Also, a complete set of guidelines can be found here. Please make sure to go through it before posting in A&D.
P.S - Try not to go overboard with the promotion of your youtube channel on PC. We have a rule against advertisement of youtube channels. So, if you're found making too many threads/posts that are merely an excuse for you to promote your video you'll most likely get infracted for it. Or, depending on the severity of the case, even banned. So yes, be careful!
