Must say, although I normally avoid looking at most digital art (a good portion of it looks like it was done on paint!) this is exceptional, reminds me of Giger (my hero) except without the phallus! Brilliant, you have porven me wrong that all digital art is boring and made by talentless arses who can't be arsed to pick up a pencil. After all, anyone can click a mouse and use paint...
well the 3d effect is imho made like this:
you make the main object (brush it or make it just as you like)
merge all layers of this object if you havent done yet
duplicate it and click on the lower on and free transform it slightly (slight turning if you want to turn it into the background and slight resizing (dont make it bigger make it smaller instead ))
now do this procedure over and over again or make it like 4 times merge the 4 layers of the procedures and then free transform them again
well then you still have to do the brushing and the background
i myself am a photoshop only artist, and i can do some pretty cool stuff. but this is amazing. after seeing this peice i was just stunned. very nice, you've gained my respect (which really dosent mean anything, sadly)
i dont understand why you are acting like an asshole. you obviously have skills and people are just wanting to know how you did it. i do not think you should respond like that. also why don't you take into concideration what other people have to say. did it occur to you that other ideas are good? i am not going to say that i don't like you work because that is not true, but it is the artist behind the work that needs to change.
Indeed it is an inspiring piece of work. As far as the HOW TO'S.. I am going to take a swipe at the basics...
The document probably consisted of 6 or 7 basic, small artworks, then those layers where duped many, many times and moved to create the "train" affect, in essence, you have 50 of 1 graphic for 1 object. Do that to all the artworks, create a couple of effect layers, a couple of pen drawn flares, drop them in, in the correct orders and there ya have it. Of course, it is not only the original graphic that makes this piece stunning, it's the manner in which they where used.
I understand that someone can create something like that from scratch, but 3 hours? Nah. Plus, you seem to be at a real loss of words, and I wouldn't be surprised if you were caught one day. If you are cheating, you are only cheating yourself.
