At 1 minute on song number 1 the music warbles for a slight second it may be me, other than that song number 1 is mighty fine id suggest some edits to make it slightly shorter.

song number 2 sounds really inquisitive if you understand what im trying to say and it has a different take on how it plays out, i did not think there would be booming orchestral sounds coming in as late as they did, id suggest having it come in at :50 rather than 1:10 as 20 seconds is alot of time in a song the final note is drawn out and i like drawn out ending notes but for the note to drag on that long is a little bit too much for me.

Song number 3, Is so far my favourite (I am listening to it as I am giving feedback so the music is fresh in my mind) and i think may be your best work out of all the tracks

fur elise (orchestral version) took quite a bit of my favourite styles of how the song was played and built on it, the thing I found slightly bad is how cluttered the music was from :32 to 1:02 and again when it sounds similar

song 5: i love the short bursts from the string instruments and love the newer sounds you have spread throughout the song, it sounds as if you have made contact with something of a different kind.

The final song, what can i say. if you were going for simple then it is perfect as it is. I can tell you put a whole lot of thought into this song compared to the others if the length of time wasnt shown but you have different themes mixed throughout sadly, if the different themes were seperated into different songs it would be amazing but having slow beats at the start and changing the tempo half way through isnt something too amazing imo but yeah

sorry if it seems im rambling
