Its usually better to only present 2 or 3 photos at a time for cc, because of the time involved, but ill give it a go since you pulled the noob card.
Boat adrift is a good shot but the yellow stuff in the bottom right foreground is very distracting. I'd crop/heal/something to eitherr remove or make it less noticeable. I would maybe even try taking the yellow levels in the whole picture down--its teh only obvious yellow in the whole shot. May work, may not.
Tree fingerprint needs more image- or less. Your choice. From what I see here I'd crop closer to the unique part of the bark for a more abstract shot.
