I see the white spots on the red stripes that represent the sunlight but the floatie itself is looking a bit flat! I recommend adding some shadows to it in order to make it more “3d” like.
But it is a nice design!
Hope this helps and good luck
Edit : I would also add that the two lateral red stripes aren’t the same size as the top and the bottom one. I suggest making them all the same size for it to look “more symmetrical”.
