I'm not a pro for making sigs and other thing s like that but I think that you should remove the white lines...
you defintely got the flow going! i think it would be cool if you made the distortion squares look like they were dissolving away with the flow.. so maybe smudging them? idk but it looks good for not having done much in a while
Wow i love it. You managed the flow. I love the pixel disortion. Render looks finely sharpened! Well done
