Sig looks good.
Background looks good, effects around the main render/picture look good and the lighting is nicely done.
Subtext is nicely done but I'm not a fan of the main red text; it looks a little dark and doesn't really jump out, you know? That may be down to the gradient overlay or possibly the base colour of the text.
Also, very minor detail, but the 1px line that seperates the two pictures looks a sharp and stands out too much of my liking. Just looks a little out of place. Try something more "flat".
But yeah, that celebration is completely gay.
