The only color i see is the dress on the lil one. Sorry

You did a good job restoring the dress but maybe you should put it more in perspective and use the warp tool to give it a more natural flow. Towards the right site it starts looking cloned more and more.
I also feel taking the background out wasn't a good idea, the boy and girl seem to float now and the mask lines surrounding are harsh. Adding a slight shadow will solve the floating and using a small soft blur brush on a new top layer (select use all layers) then going over the mask lines will blend the object better with the background.
There's still enough time to make adjustments

Thanks for your helpful, comments. I took your advice and redid the right side of the dress using the warp tool. I applied a 2 pixel shadow around most everything, then flattened with a snapshot and applied the blur to the shadows. I also changed the colors some. Lots of work but worth it to improve my skills.

gud one,,,

lol this is really good!

cool
