I can't offer any critique outside of what TaintedLogic has already mentioned, barring -- it sounds like you're recording a keyboard. My advice is not to record electronic keyboards in open air. If you can get a DI box and route this into your PC to refine the sound more, it will yield FAR superior results.

Overall, I enjoyed the writing of this piece, but the muddy mixing and extreme reverb turned me off. It left some parts of the melody and harmony unintelligible.

Also, ignore what Tainted said about kicks regarding this piece specifically. I realize you were using timpanis. You may want to add in an orchestral bass drum at some points in your other compositions, though. At that point his critique will apply.

I like the drama at the beginning. The string samples sound pretty fake - just the timbre and uniform vibrato of the legato instrument immediately gave it away to me. The transition at :39 was a little rough, too, and the mix gets really muddy at around :44. Up until that point, the composition was pretty interesting, though. The mixing and instrumentation seriously detract from my enjoyment of the piece, though. The piano at 2:04 comes in a little suddenly, and also isn’t the best quality sample. I don’t know what DAW (digital audio workstation) you use, but I’m sure you can find a list of plug-ins online whose samples are of better quality than the ones you have here. As for the mixing and mastering, I have a big suggestion: please do some research on something called an equalizer. It’s a tool used for eliminating the frequencies in a given instrument that interfere with those of other instruments. For example, kick drums and basses should only use low frequencies, and snare drums, melodic lines, and pads will probably use mid-range or high frequencies. It’s really important to eliminate the frequencies that the instrument isn’t playing a lot of, because otherwise the instruments all distort each other and the sound quality of your track will turn out really poor and unclear. Hope this helped! Please PM me if you have questions, and good luck! ;)
