I just checked out your vlogs and I think you're doing pretty well. I just have 4 tips for you.
. For vlogs, I think it's best to have no text on the thumbnails. You could just find a funny picture/video clip from the vlog (preferably with your face in it) that supports the title.
2. Channel art.
I think you should get a custom made piece of channel art with at least your channel name on it. The city picture doesn't really go well with your profile picture and it's a generic banner so it's kind of a turn off from your channel. I can make you a banner. Just tell me what you want on it and what background picture.
. You've only been doing youtube for a month. Which is nothing. You already have 100 subs which is great. In one year, you'll probably have well over 1,000.
. I looked at the comments section on some of your videos. You're getting about 5-6 comments per video which is good, but you haven't replied to any of them. Replying to comments shows the person that you care and it will probably drive a few subscriptions. It could even be something as simple as "thanks!" "
" or "haha"
I think if you follow these tips your channel will be great and grow really fast.
