lots of things to improve on,
1st put a link (see my signature on bottom of this message) so anyone here can quickly navigate to your channel
2nd thumbnails design, maybe some1 in your family is willing/talented to experiment with graphics (I use photoshop to create thumbnails)
3rd video quality = dedicated video camera, widescreen video recording etc.....
HOWEVER maybe everything is fine the way it is, keep going & have lots of fun
