ok so i just whant some tips,
when i make/write songs with just an acoustic product it always seems so plain how can i improve this
You are free to do what we tell you.
There's lots of things you can do. Use dynamics, put more emotion into your playing, improve phrasing, etc. Also, are you just strumming chords? Cause then you can fingerpick, arpeggiate, and pull riffs out of chords.
If you just make a song with chords try arpeggiate as brasuca6 said, add in some hammer ons, accentuate certain notes. Remember, even with the same chords two songs can sound very different.
