This piece is very intriguing! A multitude of questions pop into my head, questions like what do the numbers represent? Why and how is this man walking on this stream of numbers? Why is the man apparently invisible? And the best part is none of the answers to these many many questions aren't even hinted at! On a technical note, beautifully done! No seems visible between any of the elements. The near monochomatic color scheme works well to envoke an almost, but not-quite ominous feel, a feeling supported by casual stroll of the man. If I had one suggestion, it would be to add to perspective to the number stream, possibly through focusing at a certain depth and blurring in front of and/or behind. Although honestly, having a smaller depth of field isn't needed, the piece works wonderfully as is. Hope you find this crit helpful in some way.
