A few things that might improve your image:
To me your image appears unpleasing in terms of colorchoice. Especially the green towel is very distracting. Try to bring a consitant color scheme into your image. For example a domitating or lead color (possbile the red ceramic) and 2 or three fitting sidecolors. You almost have it but the green is like a punch in the face.

Both towels look very unnatural folded. The wrap around the metal ring is alright but they spread by far too much at the bottom.
You should rework some scale issues (already mentioned).
The toilet paper looks very unnaturaly torn.
You might want to consider a little rework on your light setup. In case you are after a nice magazine shot style you would't want to have such sharp, hight contrast, hard lights.
Keep up the good work,
Benjamin
