In more civilized terms: the script is certainly nice, but the phonology you posted is not at all plausible. Your language contrasts { a ä Q, which is absolutely unheard of. Neither the contrast between { and front a nor the contrast between front and central a ever happens in natlangs; this is because backness and roundedness distinctions are simply less audible in low vowels. It is worth noting, though, that a contrast between { a Q is attested, and certainly workable.
The second problem is the seemingly arbitrary nature of length contrast and the mysterious series breaking of some consonants - why does the language have dz\ but tS? (Addendum: I cannot load the image at the moment so if I am remembering this wrong please ignore the previous sentence.)
As for the actual script itself, the question is what kind of feedback you want. If you are interested in naturalism, you will probably want to come up with a history for the script. If you want our opinion on the æsthetics - it is certainly original and well-designed. It is not necessarily my style, but that's personal anyway.
I understand what you are getting at, the problem is that the conlang is not of my making, and the people I made this for aren't particularly experts at conlangs. I will be sure to pass on the advice to them, though. It's obvious this is probably a really stupid phonology, seeing as how angry you became

but I am not the one working on the conlang itself. I was seeking mainly feedback on the script, considering that the conlang itself can be changed to be more realistic as you say, and so will the script, but the script itself formed through a system of hieroglyphics which were composed of logograms. But please, tell me what you think would look good, how it could develop and all that.
