Man, I'll say this again, I wish I had a camera like that. 🙂 What model and brand is it?

In regards to the video, nice job. Some of your shots were wonderful! I'll admit though I had no idea what was up with the "Johnny Thunder" segment in the middle: the dialogue volume and clarity was inconsistent and the music was drowning out everything. You really, really need to make sure that the audience understands what your characters are saying. You might understand it perfectly because you have prior knowledge of what they're saying, but I found it quite difficult at times to discern what was said.

Breaking the 4th wall was funny and I thought it was fresh in this case, good job. 🙂

Like it has been said before however, you really need to get your grammar and spelling under control. In the dialogue and such of course it's not a big deal to use slang or sentence fragments or etc, but for publicity messages or posts like these try hard to make sure you spell things correctly and apply proper grammar and syntax. Spelling Saturday as "Saterday" in your video just looks like you made a mistake. Regardless, please, please put some punctuation marks and capitalizations for proper nouns in your posts. 😉

Getting better, as your work progresses. Technically, you could fix underexposed back-lit faces. This is extremely cheap thing to do with a bounce board. Just get a large enough board (say, about 3x5 ft; even a large pizza box will do) and paint it white (flat ceiling paint works best). You have to make sure you can clearly see the face(s) of your actor(s). The outdoor scenes simply don't work if we can't see the faces of people who speak. It broad daylight, it is impossible for a person NOT to see a face, no matter where they're facing. Therefore, you must make an effort to fill the back-lit subjects with extra light (bounce board will work) to make sure their faces are visible.

As for sound, you'll soon have to invest in a cheap microphone. If you want to make this look and sound better, you'll need additional guys, to record the sound. A decent microphone can be had for under $20 (Look at Nady SP series), and if you have a laptop, you can bring it to your location, hook up your microphone to it and record audio separately into the computer while recording video. The sound won't be ultra-professional, but with some proper boom operator work, you'll get much more consistent and usable audio, especially for the dialogue. So, you'll need a sound guy who'll record your sound, and a boom operator, who will hold your boom with your mike.

If you choose to go this route, you will obviously be bringing more and more gear to your locations. In addition to the camera and tripod, you'll now have a laptop, mike (with boom and cable), headphones and a folding chair for that sound engineer to sit in. If you begin recording audio independently, you'll need to buy (or make) a clapper board, to make it easier to sync video files with the sound files in your editing software. If you have no cash, you can just have someone clap his/her hands in front of the camera (and near the microphone).

Also, like has been said before, bad spelling and grammar simply don't work. I'm sure this is the usual teen rebellious thinking, and I'm sure it might get some acceptance among the limited circle of other teens in your vicinity, but if your audience is YouTube and the web, you'll need to find another way to be rebellious, 'cause poor spelling simply does not work and makes you come across less smart and cool than you actually are.
