Hej Behindert, phantastic sound and music as always! Your best sample so far IMO. Can't hear any big difference to a "professional" recording on my headphones. The guitars may be too middy, but like the others said, it's hard to say without vocals.
Also the drums sound killer! Very natural (e.g. the blast beat part - almost no snare). Do you use any MIDI patterns (like EZDrummer) to trigger your samples?
Guys like you are the living evidence that you don't need a 100.000$ studio to produce great tones!
