A word of advice - two things actually:

1) If you really don't have a company (a legal entity) don't say so, makes you look very unprofessional.

2) When saying tech demo, what's the technology you are presenting here? Mostly you are using templates and forum contributions. Even the sound(s) are from templates. This makes you look unprofessional.

Clearly state what is your creation and keep in mind what/who is going to be the audience for this demo - and remember - the devil is in the details.
