Without and SBS there is really know way to tell you how to fix the distortion issues on the sitting person. Distort/Warp/Puppet could help correct the odd body angles(his faded outline edges are a bit weird compared to the rest of the realism in the room.. also the lack of shadows cast by the standing figure makes him float...

While the concept (love the room walls) is quite good, the execution is a bit muddled. A little tender care might help this image a lot. (Good Luck)

at Level 10.. we would expect a little more... u didn't do shadows, juzt cut-n-paste.. it will be difficult gain votes

I know it doesn't sound good to hear, but just a frank comment, hope u not angry
