Yeah. Not bad an idea, but ...

Some nice work here.  The dolphin looks very good.  
The porthole looks nice, but it seems like the glass area 
should be bigger and the metal rim sized down 
accordingly.  The wood texture works well for a 
background but I think it might look even better if it 
were broken up into boards.

A simple but effective image.  It needs a bit more work on the textures.

From delfeld@mailcity.com:
Centering is an effective way to focus attention on the center of the image (the
dolphin).  Try taking another render with the camera looking at the left / 
right / up / down and you will see that the circular effect still brings the
eye to the dolphin, though it is not centered in the screen.  Also, try
changing the shape of the portal to be a triangle or square or other symetrical
shape and it will have the same affect on the center of attention in the image.
 Next, try breaking up the shape. . . use a bunch of unconnected lines (without
a background) resembling the shape of a circle / triangle / square / etc.  More
than that, you can then move the lines in and out, still retaining the same
centered effect.  Then try eliminating some of the lines until you no longer
have the same sense that the dolphin is the center.  Or you can start rotating
the lines, or try making the lines into shapes or parts of shapes.  Even the
lines of the dolphin begin to become lines that bring attention to the
dolphin.
