hey man ! glad you like the piece. i think explaining step by step how i did this piece would take some time and i surely cant remember every stroke or action i took/made.
basically i just took the picture and added the perspective lines to position the vectors on top of it so it would "fit" in the whole composition. i think that would be the main step besides having the concept or idea of the piece in the first place. the rest is trying out if it looks ok or works.
as for tools i used photoshop and illustrator.
hope it helps..
