Yes, sorry if I was confusing on this piece. It is actually the photos I used to do the artwork called "decline of Babel myth" shown also in this Deviant gallery. It's a "before and after:, also call a "making of".
Hope is more clear now. Before and after are very appreciated in matte-painting field because you can see exactly what was added in the image when it's a set extention like this one.
I don't think that's an appropriate comment for someone who obviously put time into doing something. If you have constructive crit, then that's one thing. But you're a complete moron if you leave a comment like that and you don't even know what you're looking at.
