I had forgotten all about the flaming dog comment, Bud. Knew you were kidding there anyway.
I'd need the context for the "Seu" part as it could refer to either "his, her, their" or, what I would guess, "YOUR." Likewise, the rest of the comment is really open for interpretation (Your work is shit vs. your work is THE shit) but I'd take it as a complement.
Assuming that you made the video, he is saying that your work is the shit (good, iow). Second part is pretty straightforward: "Principally (primarily / basically) for (the) Mushroomhead."
