1: cut out part of the dollhouse using pentool and pasted it on the melon source
2: cut of part of the dollhouse using the pentool and pasted it
3: Used warp too shape the dollhouse like the melon
4: duplicated the bottom part of the dollhouse to make a straight floor level on the bottom room.

1: Used the waptool to shape the second layer of the bottom lvl of the dollhouse
2: Used puppetwarp to shape it a lil more precise
3: created a white circle
4: duplicated the white circle n made it purple and transparent so i could see how small i wanted it.

1: here u see the white circle i created.
2:copy pasted the wood source on it to cover the circle shape
3: made the selection of the circle.
4: copy pasted the woodentile circle

1:added a bevel and emboss to the circle.
2: turned the circle a bit to have the lines follow the floors
3: as u can see i adjusted the color of the stones at the bottom and made them more straight. im filling up the bottom part of the stones here too.
4: Created a circle n filled it with gradient tool.

in these last steps I have put the settings of the gradient layer to softlight and dupliated it.. changed the opacity somewhat and added a little blur to get a lil more dept.

1: used pentool to cutout the melon , flipped it and put it on top of the other melon after making it a bit larger in free transform
2: cut a square arround the melon from the first source, flipped it and put it below the melon from step 1 here so I could have some shades from the original. also made this one ofc a little larger.

3: erased parts that I didnt needed and added some shading here n there..

then last to finish it i pentooled the dollhouse again inside the melon and tilted it a little bit.
