The most obvious thing at this point is the anodization temp. It is 10-15F too high. Ideal range for LCD is 70-75F. Higher anodizing temps promote faster dissolution, which could explain your results.
Also, judging from the photos, you made the connection to the aluminum pieces by using sometype of square piece of aluminum. The shape can be seen in some of the photos. Those photos that have color within this square indicate a poor connection to the aluminum. The area under this 'square' anodized and blocked the current from reaching the remainder of the piece.
You have to make sure that the connection to the piece being anodized is watertight.
It may be an illusion, but the smudges in the center appear to resemble finger and hand prints, while the darker edges seem to be what I've run into when I've allowed the part to dry while it is still being processed. This is especially true when removing the part from the dye tank. The metal is at 140F which causes the surface to dry out quickly. It also occurs during other steps, so what I did was between each step in the process, keep the aluminum in a bucket of distilled water until you are ready to go to the next step. For instance, once you degrease with the SP, rinse, and let the part sit in a bucket of distilled water until you are ready to go to the de-ox step. Not only does this serve to keep the part wet, but adds to the rinse process and allows the temp. of the work piece to drop without drying it out.
