That's okay, but when'er you have mainstream house, they have things to make 'em flow better. Transitions, filter sweeps, 'n' all that jazz, but I don' think it's that repetitive because those decorations help. The decorations you have aren't that opaque, 'n' it causes problems 'coz it makes everything seem more problematic. As for the 40 seconds, it's the 40 seconds at the start, an' if you look at the soundcloud link you'll pro'ly see what I was talking about.
Also, you don' have to change your synths or anythin', you just gotta add to what you have so that it flows better.
Basically everything Neblix said is brotally true.
