You will need my png mask 0085 and jpeg mask 0018.

I used a drop shadow of vertical 0, horizontal 5 opacity 75, blur 10.

Open a new transparent canvas 750 by 750 pixels and fill with white.

Paste element 46, resize 55%, position and apply the shadow.

Paste element 45, resize 55%, mirror, position and apply the shadow.

Paste element 47, resize 55%, mirror, position and apply the shadow.

Paste element 48, resize 40%, mirror, position and apply the shadow.

Paste element 55, resize 35%, position and apply the shadow.

Paste tube 1, resize 22%, position and apply the shadow.

Open my png mask 85 and paper 2, on the mask select all, float and defloat, copy the paper and paste it as a new layer on the mask, position so the paving at the bottom is inside the selection, invert the selection and hit delete, deselect, copy the paper and paste it at the bottom of your tag layers just above the white background.  Duplicate this paper, resize the original paper another 80% and mirror it, position so it shows below the house and position the copy towards the bottom.

This is what you should have now.

Paste element 44, resize 15%, position just above the house and apply the shadow.

Paste element 39, resize 10%, position and apply the shadow.

Paste element 37, resize 10%, position and apply the shadow.

Paste element 41, resize 7%, position and apply the shadow.

Paste element 47 again, resize 30%, mirror, position and apply the shadow.

Paste element 28, resize 12%, position between the window and tube just to the left of her and apply the shadow.

Paste element 70, resize 12%, position and apply the shadow.

Paste element 71, resize 10%, position and apply the shadow.

Paste element 68 on the top, resize 7%, position and apply the shadow.

Paste elements 1, 3, 4, 6, resize each 3%, position where you like and apply the shadow.

Check your layers now and get them nicely in position, add a few more elements if you like!

Open paper 21 and apply my mask 4 to it, then copy and paste right at the bottom just above the white background.  Resize 55% and duplicate, position on top left and the other towards the bottom on the right.

When you are done, add your copyright information and text and export on a transparent background as a png.
