3 of your 4 were really good. Here is my feedback on the three selected thus far:
Entry #3: would it be possible to add a warm yellow color to some element of the logo - like the sky? Also what about a version that has another boat instead of a sailboat? The boat would need to be simple outlines like the current sailboat.
Entry #6: really liked this one as well. Can we get a version that makes the fish a bit skinnier? Similar to Entry #7, but not as skinny/small and keep the curve of the propeller?
Entry #7: Looks great as-is. One version I'd like to see is instead of the square in the background, change it to a circle like Entry #6 but keep it the same size as #7's square.
Hey buddy, Can we get two revisions of #46 and #60 with the fish not smiling? I like that they look like fish (and not yin-yang signs), but I'd like to see the smile toned-down a bit.
One more separate set of revisions of #46 and #60 would be to add an "edge" or stroke to the backs (or tops) of the fish similar to that was used in #47.
Also for #52, I'd like to see a version of this with the colors used in #3. Another request is to see both #52 and #3 without the extra wave piece on the right site. One last question: is there another boat that could be used in the #52 design?
Just thought of one more modification or revision to #46, instead of 4 fish (or propeller blades), try 3 fish. Three is a more standard number of blades on a propeller.
