hi pixy!
i put #33 in the ranks, but i also like the logo on the black background. the logos with ranked not interested are there for the folowing reason: the fish looks a little bit too slow.
#32 is also nice, but i prefer not to have a shark in the logo, as it creates an impression of viciousness.
the only concern i have about #33 - #35 is the scalability of the logo.
nice work!
