1. Quality> Quantity, The Quality of your videos is one big part of it, if someone clicks your video and the audio is too loud, fuzzy, the image is blurry or distorted they are going to either close the video or leave a comment and not watch it. I noticed your videos are 480p Not too bad though.
2. This is one that always pops up, try be original and i don't mean you have to think of a whole new idea just try do what nobody else does, a good one for that is to be yourself!
3. Are you using nice thumbnails? People tend to click on videos if the thumbnail looks promising. I noticed that some have enticing thumbnails where others where part of the game that youtube picked itself.
4. Are you titling/tagging your videos correctly? Using misleading titles is bad but also using to many short words such as "a" "the" sometimes get cut out of a search. Tagging your videos correctly is key as-well as SEO (search engine optimization) will get your videos more frequently come up depending on key words and what people search for.
5. Key uploading regularly, this will get you an audience, and with that audience you want to listen to them so if they suggest something it could be worth listening to them (:
6. Create a unique name, have a banner that stands out and a good YouTube picture. You pretty much got this one covered.
7. Social Media, share them on facebook, twitter, linkedin you name it!
If you're doing all this quite frequently and sharing your videos on social media sites your bound to get more views/subs eventually, YouTube is a hard one with so much similar content and small channels content sometimes don't get recognised but keep working on your videos and you'll get there eventually. Ill go sub to you and comment on some of your videos with feedback.
Remember the amount of effort and time put into videos the more likely they are to be more popular, and if you don't enjoy making a video and doing it "just for views" there wouldn't be much point if your not having fun!
I have a small YouTube channel with 400 subs and get around 500 views a day, try interact with your subs and post content they might like to see, Hope I helped a little
