Everyone has their own interpretation of things. I would suggest you look back through the many photo contest and other Disney threads to see what "other" types of things you could try which you may not have tought of before.
In the meantime, for a critique - since you asked. This is just my interpretation or thoughts on how you might be able to make your pictures more interesting. All of us are always learning.
If you have a basic editing program, maybe try the following:
#3 try cropping off the left side of the building and tree, to just beside the clock.
#4 try cropping off some of the sky and area to the right of the frog, and (if you're good at Photoshop) get rid of the crooked lampost, leaving just the frog, buildings, chairs, and spray.
#5 first, straighten the picture; second, crop to leave just a little on the bottom of the metalwork base, and to the first line of the top of the metalwork. When you were taking the picture, using a larger (ie lower number) aperture would have blurred the purple flowers in the background which would also look really nice. This might have worked best if you stepped to the left a bit in order to get that big bunch of purple flowers in your picture. Another angle which might have been interesting would have been to shoot it from the ground looking up. (This could be a nice picture for the upcoming architecture contest, possibly.)
Last picture, you could possibly crop tighter to show just the characters and castle.
These are just suggestions. Play around with them however you like and see what works best. Maybe after all is said and done you'll like them as they are. They are very nice to start.
Here is a thread on
Composition if you're interested. As you can see, I'm working on it myself.
