You got a really 80s sound, I've just finished listening to the first song and I can definiatly hear a lot of Megadeth influence in it.
Something I'm bothered about is a few things though ;
The drums are in my opinion too high in the mix, there's almost no bass at all and the vocals could be higher.
The drums themselves take up too much of the bass spectrum, what can be done is fixing so that the bass frequency on the bass-guitar is higher, keep the lower end to the bass-guitar and the higher end (of the bass spectrum) to the drums. This will make both the bass-guitar and bass-drum stand out but not clash together.
I got a feeling a lot of this comes from having it on youtube though, you should upload it to bandcamp.
thanks for the feedback! i must say that those demos are badly mixed, and we're actually working on the final remixes. we got a nice remix going on for Cold Blooded Justice here.
