My first impression was that it sounds pretty good. nice seperation between the instruments and the bass blends well with the guitars... almost too well! haha.
The only things I would consider tweaking is the kick drum and snare. The kick sounds a little puffy, try some subtractive EQ on the mids (300hz-1khz) paly around in that area until the kick feels a bit tighter and dont foget to use gain makeup so the kicks balance in the mix is not affected. As for the snare I think it could come forward a bit more in the depth of field. Ease of on the reverb somewhat and add a touch of high shelf to the highs (perhaps 8khz+) just a touch though, no more than 1db.
