as you can see, there are little individual stroke marks from the clone brush in certain places. to fix this, you can select the patch tool, and then select the areas that have individual stroke marks. one they are selected, click int he center of the selected area and move it out into the space directly to the right of the girl (the unedited space.) this will make it look more smooth. heres an example i did in about five minutes (i took the one you already edited and then made it look smoother.)

ya, thats better, but you missed a little bit of choppiness on the right side right below the chopsticks. also, you can just use the clone tool to smooth out the choppy areas around the fingers too.
