You have made a very complex image here and I see what you are trying to achieve.

IMO there are a few things that need to be corrected if you have the time.

The masking/cutout of the lady on the left could use some refining (if you can try using layer mask they can help refine the cut). The floor is a little too Cloned looking, you could try to use the cut and paste-over in small section, then position the bricks so they line up (which takes a fair bit of time) or try to get a full brick floor. The base could use a bit of perspective fixing ... the sides are slopping out a bit too much, I would say the upper-far corners could be moved in toward the center of the image a bit (using the Transform tool and hold down the Ctrl key to Free Transform individual corners). You can also see through the left hand side of the base at the back just in front of the lady (a quick way to fix this is just to duplicate the layer until it becomes solid and then merge the layers together). I know this is a lot but your idea is very nice and I believe you are headed in the right direction. If you have any questions just PM me

THanks VERY VERY MUCH !!! it is through this type of feed back one can grow . I wont have time to fix. but i will take on board your tips for next time...
