Definitely an everyday object! The idea works - but the photo suffers from loads of compression problems. You've used only 16k bytes - try to get less compression problems by saving the image much closer to th allowed 150k.
While I think the idea of using a toilet for this challenge is actually pretty good, I'm sure the execution could be done better. The angle presented is not altogether interesting, something lower at an angle would work much better imho. The chosen composition does not present the subject in a very interesting way.
It´s good for you that you seem to clean your toilet properly (or is it someones others). Dont find much creativity in this image and it seems pretty noise and unsharp.
While it is an everyday object there really hasn't been anything done to make this an interesting composition. However, I must give you compliments on how clean and inviting this toilet is. I would relieve myself here any day. :)
