Proxima Centauri

Hi to all!

Here is my latest composition based on an extrasolar planet that may support life. 
The previous ones were "Tau Ceti" and "Iota Draconis (The Dragon's Quest)".
Am planning to combine these into a symphony or suite eventually.

The score is designed for midi playback, hence the strange note lengths and dynamics. 

Think I probably need to allow more time for winds and brass to breathe?

Also my bass-line in the celli and doublebass is really boring: so perhaps I should change it?

Looking for some feedback on how realistic the orchestra sounds, and what further steps I can take to improve this?

I used MuseStrings and MuseWoodwinds with Berlin Brass. 

Haven't done any stereo panning yet. 

Think I may have pushed the dynamics too high in the climax at the end, as it sounds like it's clipping to me.
