I'm not saying you shouldn't have an install. I usually have loads of kit in my own cars ( kind of between installs right now though ) but with a bit of thought you can create something that has visual impact, but at the same time looks like it belongs in the car.

That's what I was (badly) trying to say in my last sentence.
You obviously have some talent for this sort of thing, you can see that as the finish isn't bad at all... uneven in places... but pretty good. But all you seem to have done is create lots of individual pieces and plonked them at random around the car.
The link Pete gave shows what can be done without going OTT, but whilst still remaining respectable, individual and unique.
Bigger doesn't always equal better.
And please note that nobody is getting at you, nobody is trying to be horrible for the sake of it. But you asked for opinions and that's what you got. Don't take it to heart and don't ask if you don't want criticism.
