need some help
 

Can someone give me some advise on the ending of this song?
It doesn't sound right or am I to hard on myself? Do I have to use some different notes in the end melody? Is the sound right? Does somebody have another idea? I still need to record the vocals, so maybe some vocal fx over it will distract from the melody..

It's about the first song (needs vocal)

Any help appriciated :)
