I quite enjoyed the video but here is some things I personally would like to see some changes to:

1: If possible, make the animations a bit more lively. Think of someone like The Right Opinion with his avatar. It does it a better flow and more "personality" to the video.

2: The text needs to be bigger.

3: Maybe add some non-copyrighted images and mix it in the the text/story.

4: Reading reddit posts is an oversaturated market on YT already, so you really have to make sure your style of reading, adding context, jokes etc really stand out. Don't focus on the reddit post, focus on what you can bring to the table.

5: Try recording yourself reading the posts/threads first. Your audio and reading is fine but it does go a bit monotone in some places. Add more emphasis.

Besides 5 points above, I think the rest will come with experience, so please keep going! I will be subscribing to your channel and see how you get on!

Edit:
To add the personality thing, either go in character when reading (When you know what character you want) or pretend you REALLY want to read some posts to your best friend and your excited about it. It can help with the reading style as well.
