Quote from Relios
Your videos look pretty good! The only thing I can think of is to work on your impromptu speaking, but that will come with practice. Another thing is to try and do a co-op let's play or at the least one video with another youtuber who has a bigger fan base then you, this will most likely increase your subscriber base and view count. Last tip is to always ask for likes, favorites, and subs. It may seem like a whoreish thing to do but at the end of your video just say like "Don't forget to like,comment, and subscribe" and then whatever you normally say to end your videos.
I actually prefer to say something like "Remember to leave a like/dislike, comment and subscribe if you wanna see more of my videos!"
Makes them see that you're just reminding them to like/dislike/subscribe/comment, rather than begging for likes.
