New stuff by myself, with ma new rectifier. (plus it's heavy)

The synth sounds pretty dry at the moment. It's definately a taste issue, but I would try some verb/ delay and maybe even some very subtle modulation to make it just a touch more interesting on it's own. Also, before the band kicks in and it's just the one synth I would try to mix another synth playing the same line just for some texture.
The guits I would say could use a touch more gain/ saturation. At the moment they're sounding abit lo fi. Couldn't tell you what I would do to them in the context of the mix though.
The drums and bass are sitting nicely together, just a touch of fine tuning on the balance of the mix is missing. Actually, the guitars could come down a touch too.

Not bad dude. I like the track, will check back when the vox are done.
 
The guitars sound like you've got a clean DI going on in there. I'd also say they have a bit of a weird ringing sound in the high end that sounds like a very sharp E.Q. spike, and doesn't sound incredibly nice.

I'd say make the kick slightly less clicky.

I like the rest of the kit, and the bass sounds cool aswell.

I like the synths. Love the really melodic section at like 1:10 ish.

Sounds sweet overall dude!
 
Thanks dudes! I definitely recorded the 5150 with a little less gain than I normally do, not used to blending the mesa with it yet.

I will give the synth verb a go and see how that pans out. Thanks for the suggestions!

With the opening synth should I do another similar one down an octave?
