Hey 13, the videos are pretty good
One suggestion though, at the start of every video you have a title screen, some of them remind me of like a power point presentation title or a windows movie maker effect and feels really out of place to me
And the FNAF 3 #1 video title screen is fire orange arial font text with a slightly lighter orange drop shadow on a puke green backdrop, i guess if you were going for a horror theme orange and green kindve makes sense but it just doesnt look good
Try to avoid arial and times new roman unless its a formal presentation or if theres a lot to read (you can get a bunch of fonts from here to use:
http://www.dafont.com you can also search for the font that the game your playing uses and use that for the title font)
And avoid the following color combinations:
Orange/yellow on green
Green/blue on red
Purple on green
And vice versa
Those color combos are hard to read or just clash badly
If you can you should make a logo of some sort with photoshop or gimp and just put that at the start of your videos instead of a title screen, the logo could just be something simple like "Ranger Plays" in a nice font/color with some sort of stylization and have the logo of w/e game your playing in that video behind that text
This seems like a pretty minor thing, but that title screen is the first thing someone will see when watching your videos so it matters a lot more than it should
