Cant listen to the track I dont have Guitar Pro, but honestly I'd just start writing, trial and error has worked for me...I dont consider myself the top notch when it comes to writing, but I've improved just by trying to write something and just tossing it out there for people to critique etc.
The song sounds like some Dream Theater stuff.
Maybe try doing some variations to all that verse-chorus-verse structure, other than that I find nothing wrong with your songwriting.
