looking for some advice with my render..

[jackdicker]

Hi guys,

 

Hope you can help. Im trying to push my render further to become more real but I feel I have reached a road block at the moment. As you can see in the photo I have a vibrant pink sofa/stool/poof thing that I'm trying to get looking the best I can. I seem to be getting areas on materials that seem to be a little pixelated, kind of gamma effect going on. I was wondering how I could smooth out materials? just general advice for enhancing the image would be much appreciated
