Hey welcome to the forums
I cant watch your videos properly right now as my audio is off at this time of night (I will do tomorrow though and post something then as well) but based solely on first impressions of your channel and your videos in silence there are a few things you could do.
I suggest you get a background, something that represents you and what you do in your videos, you could try a premade one from one of the background websites or go a step further and do your own if you are handy with graphics programs. If you plan on keeping your current icon with Energy Edit written on it you could do one themed similarly so they match.
I checked out your intro video you uploaded and I think it could be a lot more effective if it wasnt flicking between black and white, that will do peoples eyes in
I think something more subtle could be better, just the text on its own with the black background would be easier for me to watch.
Your vlog video would be a whole lot better if you looked directly at the camera, I am not too sure if you're chatting to someone online or something but in general it is best to keep your eyes on the camera lens, pretend you're making eye contact with a person and as if you are talking to someone face to face.
You have a decent username there too.
I will have to watch them properly tomorrow with audio to say anything else but I hope that helps
