If I may make a suggestion, your instruments, like the drums especially, are of really poor quality.
They sound like an old 80's casio drum machine. One of the most important part of making your own music, is only a small percentage the actual guitar parts. Drums, bass, keyboards, sound effects etc... should all be the best they can be also.
If your serious about making your own music, then I suggest using a better software package or better sound samples.
I'm no musical genioius, but I have been playing for 20 years and teaching myself Audio software for about 7 years. I recorded heaps of tracks just like yours and they were great for learning and listening to my own mistakes.
In my opinion, you should not bother re-recording them, I would push yourself to write new tracks, with the information you have learned from this experience. Try thinking about what your song wants to achieve. Do you just want a guitar soloing over chords for the entire track ?
Or do you want an intro that builds up to a peak and drops down to an ending etc.... Song structure !!
Here is a link to my myspace listen to them and tell me what you think of my music.
I Can't just tell you what i think of your music and not give an example of where im comming from. Its easy for people to criticise other people music, but rarely do they produce examples of their own music. Im not saying my music is the most awesome **** on the planet, im just like you but maybe with a little more experience, that im happy to share...
Keep writing new songs, new songs is where its at, trying to re hash old ideas, is a great way to live in the past and never progress...
The wounded guitar is my favourite track so far. I got more music but there not ready yet !!
