I would leave them the way they are. Farewell has to have the ship leaving in it, of course, and her size just emphasizes how far away it is going (in my humble opinion!). Can't really tell about the block with ducks, but looks like it blends well enough in this photo. If it is too striking a difference to you, make another and use this block to make a pillow - it would certainly look great alone. They are all so wonderful!
