They are great. Like all photos they depend on subject and composition.
I really like the way you captured foreground and put the coaster in the background.
I have made these myself from 360 panoramas. Actually this format is a clever distortion on a panorama. I believe I used the program Hugin.exe to do the distortion, but it has been a while. I suggest you take panoramas with the camera and then convert to tiny planet with software so you have more artistic control.
Suggest you post a normal photo with the tiny planet. Either the entire pano or an artistically cropped version of it. When both versions are displayed together, the "eye" can discern the information easier. Keep up the good work.

Stricker's Grove in my closest amusement park. Isn't it great?
