Ok so first of all....AMAZING CHANNEL!!!! I liked it so much I subscribed! Before I get started on the criteria of the review let me mention a few things I noticed right away before I forget.
1.) On your "How to mould a prop part 1" video. I always thought it was spelled "mold"? Or is that just an American spelling variation? Regardless, just putting that out there in case it is a typo.You don't want a troll criticizing the amazing content of that video for a stupid spelling error. 2.) The lighting on that video is "passable" but it has that orange-y "tint" or "glow" when you use your regular indoor lighting which for me is no problem but your videos are so great I would hate for a know it all YouTube viewer to disregard your content because of your lighting. I honestly think if you invested in some lighting equipment you could take your channel to your next level in terms of quality.
3.) on the intro outro video in your signature. It's really get and I totally dig the retro gaming style (Which just so happens to be "in style" at the moment). However, the intro is a bit long for my taste.I would recommend cutting it to about 7 seconds or less. But that's just me preference so take it with a grain of salt. When people want to see an instructive/educational/informative/tutorial type video, they want to get to the point and quick. I can't tell you how many times I've read comments from viewers saying..."Holy hell, 1 minute before you began the tutorial!!! Shut up and show me how to blah blah blah". The outro is perfect in my opinion.
4.) In your N7 helmet video..When you're basically showing still images in the beginning...Try taking the picture in landscape and not portrait. People HATE seeing black bars. If not possible, use the same image in the background and stretch it out with a "blur/distorted effect" to fill in those black bars/gaps.
5) In the same video, I would recommend using a different font. People pick up on those little things and shows the effort you put into your videos. Because you obviously have a talent and it's just a small touch that I think would pay dividends.
ok now onto the review criteria!
1.) The banner itself looks great! However, I think it doesn't really reflect what your channel is all about. At first glance I would have assumed you have a retro gaming Let's Play channel.
2.) Audio is perfect for my ears. I'm not one of these individuals who put much thought into audio. If I can hear you fine without any background noise...That's good enough for me. The occasional "popping" sounds don't bother me as long as it's not a habitual thing.
3) 1080p, enough said. Although I mentioned the lighting could use some improvement (I'm guilty of this as well) try recording next to a window during the day.
4) You're informative and very knowledgeable when you speak. And you don't have the problem I have with the "ummms" and "ahhhs" so that's a definite plus!
5.) The thumbnails are the only real negative I found with your channel. I would recommend you design some kind of template to use so they all share a common theme. For example, mine is the "comic book" effect. And I notice you like using the "game over" type font which is great. Try to implement that a bit more. If you'd like, I can help you brainstorm and make a few variations and see which ones you like.
I hope this helped and remember...Take what I say with a grain of salt
but i guess after you practice it a bit and do a little prep before hand it all comes out pretty smoothly!
