The piece was a bit repetitive for my tastes. There is a suspenceful element, but no climax to it. Around 1:20, there seemed to be something new, but it was not pursued.
Again, this piece was a bit repetitive, but not nearly as much as number 1.
This was my favorite so far. There is a hint of another song and the melody seems to rely more on the right hand the two previous ones.
Shortest so far, but then you knew that. I liked it. It seemed to have elements of the Nocturne in it. A bit sadder than the other 3.
After that, you have exceeded your alloted data transfer. Perhaps you could ask PianistSk8er to host some of you stuff.
