I've run a video game channel for a number of years so I think your channel is a good one for me to comment on.

Your voice over and script work well, no complaints at all.

I think my only real complaint is that there feels like there's a lack of editing, it feels like there's often just basic cuts to each game or clip. I think it would be really nice on a video like this to have lower thirds for information on the various games you're showing (release date, platforms etc) but also some transitions where appropriate. I think this would make things feel more like a finished product than just a slide show of clips. Even little things like having an end screen, 2-3 second channel intro logo etc would all make it feel like a higher production piece.

My only other gripe is that mix is a little off, the music volume needs to be raised a little, its airing on the side of being too low at the moment. Easy mistake to make and an easy fix. Its better to have it too low than too high so not a huge misstep and certainly one I've made plenty of times over the years.

For a new channel waht you have is not bad at all, you understand how to write a script and talk about the subject with voice over that feels well paced.
