Needs work
It's really hard to get a really good classical rock sound without guitars. First of all, there aren't too many people who know how to get FL slayer to sound like a real guitar, one just off the top of my head would be jrayteam6. I'd suggest trying to find some FL Slayer tutorials out there, using a real guitar, try finding a better guitar VSTi (I think I remember seeing one somewhere, a little while ago) or trying to work with different virtual instruments. A rock song usually sounds pretty simple, but most of the time a lot is going on. As well as the lead guitar, there's the rhythm guitar and a bass, and drums. If you want to reconstruct those instruments digitally, you need to have really good samples, and most of the time this costs a lot of money. You could probably get some good drums by using the FPC and using techniques and patterns that sound as if a real drummer would play them, and you can add realism to the drums by adding reverb. I think you can probably improve on this if you add a bass, maybe try and get something good in slayer or search around. You could probably get a passable rhythm guitar with FL slayer if you sue it right, but the lead is a bit of a problem, you could replace the lead with a violin sample or flute sample.
Also, there's the structure of your song, once you've got your base chord progression, you can vary the lead around that to get a few versus, connect them with a second progression for a chorus, add a third progression for variation as the bridge, intro, outro, wham, bam, you're done.
Hope this helps break it down for you.
Good luck composing music in the future.
