You have a LONG way to go.
Now before you start calling me nasty & horrible names please let me explain myself. I say that with the most respect possible, as I am not saying you're channels terrible and you're never going to make it. What I'm saying is you're at a good start, however there is A LOT of room for improvements depending on your budget (Which doesn't need to be too expensive.)
So let me start off with my initial reaction, I first played your welcome to my channel video. (Now I haven't actually made one of these myself as I never got round to it, but I am planning to for my new channel.) The first 30 seconds I lost interest as you just basically spoke about this is replacing your old video & then after that you give us a list of games you'll be playing. The main issue with this is, you sounds boring! A welcome video should have HYPE! Enthusiasm! You want the person who is looking at your channel for the first time to be excited about what they are seeing, not just some clips from a game with you talking. It just sounds like you're making a normal video just talking about ideas. Honestly, you should make a script either in your head or written down and then use that. Keep to facts! Who you are, what you do! They want to know in a short period of time why they should stay and subscribe! So Keep it fun! Talk about yourself, and what makes you unique! And then throw some funny moments in to give them a taste of what is in store for them if they stay and watch your videos!
Just some ideas on that for you, now coming away from the intro, and more into your general videos. First looking your videos and what you have to offer... it's not much. Football (I personally dislike this) & Lol (Which I don't mind) and that's all I see straight away! Maybe it's just me but I like channels with Variation! I don't want a YouTuber that plays one or two games. So mix it up, have fun and see what response you get! Looking closer at the videos you have attempted to make some thumbnails, which are good but you need your own personal ones! Make them unique! Make them have your personality! The more eye catching the better!
Lastly, the commentary/editing. I am going to use the 'Top 5 Most annoying types of people in ranked League of Legends.' Not repeating myself too much, with these videos I want to find more humor & hype with these videos. You made a good effort, and since your just starting so it's understandable! It gets easier as you go along. Now, I want to talk more about editing.... ESPECIALLY when it comes to videos like Top 5 stuff. Basically what this video is, is a montage. You have thrown clips in from games and spoken over it (And it shows.) Sorry if I sound harsh but I'm doing it to be kind. You need to spend a lot of time and patience with these type of videos. From making cut scenes with the numbers 1,2,3,4,5,etc to putting in relevant clips. When I say relevant clips, I mean for example if you're talking about someone feeding mid as a champion then got some recording of someone dying multiple times! Make it funny and keep the clips snappy and short so people don't loose interest! Also, this is just a personal opinion, but with these videos I don't want to hear too much of the game audio, it's too loud in your video. So either make it quieter, or keep the clips short with louder audio.
Anyway, just hope this helps! And I would appreciate if you review my channel also!
