Thanks guys! Question - does the last one qualify as an abstract? Up to now I still don't really know what an abstract is

This was my first time to try something quite different with my fisheye lens and I liked the result.
Here's the settings I used for each shot.
The first one was with the kit lens at 40 mm, ISO 200, AWB, f8, 0.3 seconds, handheld. JPG (oops!) Converted to B&W with Picasa (filtered for dark red).
The second and third were shot with my FA 80-200, both on tripod, not sure about the WB setting:
#2 at 170mm, ISO 200, f5.6, 2 seconds. RAW converted to JPG in Picasa.
#3 at 80mm, ISO 200, f4.7 (4.5 according to the cam), 2 seconds. RAW, WB corrected in Photoshop and touched to remove one buoy in the water.
The last one was with the DA 10-17 at 10mm, ISO 1600, Tungsten, f8.0, 0.6 seconds, handheld with SR off (I must've forgotten to turn it on after using it on the tripod that night). RAW was converted with Picasa.
