1st one is interesting idea, would possibly look better if u had the other lense visable aswell,
2nd i like the yellow boats but theres no real subject in this photo, but nice non the less, if u go here regularly and the boats are still there try it again with the boats not on the bottom but more centered might produce an interesting shot idk.
3rd i agree with blackrose but nice
what camera you use?
would love to see some more photos by you , seems you got a few neat ideas for taking interesting photos.
