LOL Minute, minute league videos (new creator, tips wanted)

So recently i've been trying to get into editing by changing my content from long 30+ lets plays to short video game guides and funny stuff. Recently gotten 5 episodes of a series i dub LOL minute, but they all feel lacking somehow. LOL minute 6 and 7 are both urf related, but hold up to the mediocrity of the previous episodes.

The idea was to highlight moments from my normal League Games, and give an informative voice over to make an incredibly short video that's still entertaining. My current thought process is that i need to write more jokes into the videos, make longer videos with multiple moments, or get someone else to voice the video. I'd prefer to voice the videos myself and keep the videos around a minute

I think a big part is that my voice doesn't sound hyper-child-y, but otherwise any tips?
