Thanks for the kind words seye :]
Heres an example with my current sig.
As you can see, my render crosses all 4 points of interest (just) However you dont have to cover
ALL of the points. The 4 cross points are where the eye looks naturally, so it would only make sense to lay all things that are of interest in these points.
When doing photography, you pick a subject to take a picture of and _most_ cameras have the option to apply a grid over your lcd display to line up your subject in the most eye catching way. When making signatures, or LA's (large art) it applies the same, just imagine you are taking a photo. The light..the position...the subject (render) everything has to be right.
In hindsight, looking at my current spidey sig i would move my render over to the left a bit leaving the face in a point of interest. However, at the time i wanted it over the hands and the mutating *thing* which turns him into black spidey (it has a name, i forget it ;P)
Another quick tip which ive mentioned but i'll explain in more detail, is check the light source, when i started with the render of spider. The light source was originally behind him, with a subject focus light in front (
see) I didn't like the light coming from the front, so i used the burn and dodge tools to create the effect that the light is solely above/behind him. And added my own light (white) brush strokes over his shoulder to emphasize this.
hope that covers some gaps
Any help needed, just ask questions
And thomas, i made the grid. But it's not perfect, i just use my eye to visualise a grid over the top of my canvas. I just made one to visually show people how it's done, i will however make one now and save as psd and upload shortly
EDIT:
Made one which is perfect, measured out. For a 400x125 canvas, you can resize it for bigger/smaller canvasses. Just press ctrl+t and drag to size making sure to hold shift while doing so to keep aspect ratio. If you would prefer a more accurate one, just say the size of the canvas and i will make one for you and upload.
