Good
I wanna give you my(!) thoughts about this piece.
You will also see, that i dont agree with everything, like others did.
At first i wanna talk about the composition.
You open with a very big and strong beginning, but you just cut the level of tense you have created right afterwards step by step. There was a lot of potential in it.
The following part is pretty flat (i dont know how i can term it otherwise).
I can hear some snares and a synthie bass - but even the snares are disappearing, and it makes me feel like an outro (even after they came back very brave).
Nothing really exciting is happening to be honest.
You have wrote "For the rise of a character still unknown" - so i was expecting something else so far.
You should (in my opinion) use your beginning like it is and build upon it.
Make the following part much more energetic, propulsive to capture the energy (tremolo strings, staccatos, clusters - more dissonance at all and stronger percussion if you want). Oh and dont forget about the woodwinds - let them play flurry and fast glissandi (especially in transitions if you wanna have it chlichee), staccatos - whatever. At last let this flow into your theme, making it much stronger and double it with other instruments.
The thrid part is started by some dissonant strings is nearly the same - if you wanna have tension or suspense, you have to let the instruments be very tense. Strong constant bass, very high tones, strong dissonance, strange rhythms, crossrhytmhs are elements for example making things suspense.
I dont wanna reapeat myself too much, so i come to some other thing what i noticed.
The strings are very flaccid and could have much more high frequencies.
Make them play the staccato like some real staccato with lot more attack or velocity. The brass players seem to have a long breath too :)
Overall there is a very big lack of dynamics, in the strings and in the brass.
If the brass is getting louder, its just getting louder without the typical overtones. There are X-fade samples sometimes, where you can change this by changing the modulationfader in the midis to create some near reality swelling brass.
And missing tempo dynamics.
Let the orchestra breath (thats what my teachers tell me too).
I dont really understand the electrical bass under the whole thing - it reminds me on hans zimmers soundtrack to batman. But i just dont understand its function - please explain it to me :)
At last something about the mixing: Im pretty unsure.
If you wanna maintain a real orchestral sound, you should start by placing the instruments in the room (left, right, middle and front, rear, back).
But its different if it should be some "unreal" orchestra with electronic sounds - its somewhat depening on the situation.... whatever.
I give you a score of 7 and a vote of 4 because i dont wanna be the bad one and i think there is potential in this piece , but there has much to be done.
Work on it :)
