Okay, First I should point out that I use a program called "Gimp" not Photoshop, although as I understand it they are quite similar.
The horns were all hand drawn and hand shaded. I simply drew a shape I liked, quick and simple, the cleaned up the edges, I tend to make details like this as a seperate layer first to I can add or change as much as I like. So I the added bits of birghter white, and verious grey shades until I came up with a design I liked, Then I took that layer and copied it, if you look close there are only a handfull of different horn types. For instance look closely a the elbow horns... All four are the same one copied over and over.
As for the cape, you cannot see it in that picture but look at this one...
If you will notice, the cape part that flows behind him is a real one that I cut from Superman. What I did was selected the whole body with a free select tool. And created a new layer with just him on top of the picture. The I put the cape in behind him, between the layers. I merged them back together and PRESTO! he is wearing the cape and it apears behind him....
Shading is the most important thing, the light source will make or break a picture, this goues double for the horns. they looked horrible until I added shadows. It took a long time but it was worth it.
Anyway, back to the cape. What I did to draw the shoulder part was simply take color samples from the other parts of the cape, and then I drew(as a new layer) the whole thing, shade by shade, it only took a minute as I did it in broad strokes, just to get an idea, then I use the warp tool to bend the image until I was happy with the shape, I trimmed down all the edges until it looked about the right size, the I just did the touch ups, added, or took away, shaded the underparts a little more, I had to actually erase a whole chunk of it to allow for the hammer to show through.
On a side note.
The whole picture was colored blue, even his skin, so I had the task of bringing that back to normal, with the color tool, some burning, transparent shades... The skin was a nightmare.
So there you go! anything else?
