Hi Renderiza,
Yes, I'm another amateur musician.
Went through pretty much the same process as you - a bit of formal education at school, trombone in the school band etc. that just made me bored and frustrated. I think that's often the case, even for people with far more talent than me - too much concentration on the 'orchestral' style, and too much emphasis on formal 'rules' - not exactly inspiring if you are a youngster wanting to take the first steps to emulating the music that you like on your mp3 player!
Then I discovered "DIY punk", bought a bass the same day my mate got his first guitar, and never looked back. In many languages, we talk about 'playing' music, not 'operating' it or 'constructing' it, and I think that the element of 'play' is exactly what can open doors for people to start exploring music - without feeling self-conscious about their 'skill level'.
And the technology available cheaply now means that this can be in any style of music that floats your boat, or even 'sound design' - a also have a little hobby building VST plugins to make my own sounds to play with.
I don't play for an audience any more like I used to - but it is a shame to only concentrate on what we can present to other people publicly. After a crappy day at work, and too long in front of a PC, there's nothing to beat sticking on a pair of headphones, and disappearing into that "other world" for an hour.
I'm a great believer in Joe Meek's old adage; "If it sounds right, it IS right" - so long as what comes out is communicating a little of what you feel inside, then 'technical perfection' is just one option among many, but not essential. Being able to play 300 perfectly pitched notes a second is no guarantee that the tune will move people emotionally (I love loud guitars, but 10min "shredding" solo's bore me stupid!)
Your YouTube snippets sound pretty good to my ears - way different to my own 'style', but each one definitely has a 'theme' that captures a certain mood. They would fit very nicely as the kind of music used in film, TV and games to set the context of the action.
