#3,4,5: Need a reference to water. Perhaps instead of the mountains in the background add some water, or waves, etc? The top of the snake where it curves doesn't look symmetrical, can the curve be made not so "pointy" and a little more even (perhaps not as tall either)? Add in "3.1km" & "7km" to the left & right of the "swim".
#6: love the yellow stroke and the rattle added! Can the snake loop be made so it's not so tall. The small opening between the loop and the top of the circle will get lost when scaling down the logo. I like the new "Swim" font but it still seems to be disconnected. Perhaps because it is a different blue?
#11: Can the snake be made a little larger? The loop of the snake body can extend higher out of the top of the logo (half way) as long as there isn't the gap again. Need to remove the year. Perhaps swap "3.1km & 7km" and the "Peachland". Add "BC" to "Peachland, BC". Still not fond of the background as it doesn't look like water to me, need some subtle waves.
Also possible to try one with a solid black background behind the "Rattlesnake" and "Island Swim" so you can't see the circle and snake through the letters.
#18 Really like the snake now! Can the splashes be made a little less cartoony? The rest of the logo looks great and I like the splashes but they don't have the hard lines of the other parts of the logo. Also is it possible to change the starry background to some subtle waves or rays?
Hi Fracco, #16: The splashes don't look right to us as they are too bubbly. Could you change them to be more pointy waves or splashes but keep the black stroke
