Vocal+mastering project

[techno_7]

Hello everyone,

I've recently finished one of my first vocal tracks (with me in the vocal), and i liked it alot and thought i'd show it to you guys in hope that you would give me some feedback and improvement points as i'm practising in my new-found interest in mixing and mastering. I have put a mastered and a unmastered version on my server:

Unmastered


http://www.t7online.dk/Music/Clockwo...k%20master.mp3
Mastered

What do you think of my mastering? I didn't do any stereo imaging as i thought the track had a just fine stereo perspective, i didn't do dynamics neither, do you always have to use this?

Thanks,

T7
