Looks too empty for me... and I don't like the border. IMO, make the height smaller and stick a sprite in there! I think it makes a great BG for a Sprite-tag.
Excellent smudge settings used and great colours too. The sharpenening really adds the final touch to it. Not so fond of the text though. In these kind of sigs where there isn't a real focal, I usually dislike text because it tends to grab one's attention and steer it away from the actual smudging. Adding a sprite or something might be nice, but I like it like this as well
thats some nice smudge work bro better than mine. its a very well excecuted abstract and IMO you dont need a sprite. maybe a coca cola tho lmfao
