I watched your video. Gotta say it was pretty entertaining. Obliviously there’s some room for improvement;
 
For starters I wouldn’t use Pony Creator for your avatar. Until you can get a higher quality set of character models it’s best not to use one. Instead you can use game-play footage from your favorite game
 
It’s also a good idea to write notes for what you want to say, It doesn’t have to be a full script but just notes so to keep yourself on track and have an idea on what to say say I don’t end up mumbling or going off topic.
 
Apart from that you have a good knack for commentary videos. Keep up the good work :)

tfw you see pony generator
