And the result:
In need for the each of the four blocks on the left side a different figure inside. Here are the given figures: 
.
I managed to create two of them. The code for the remaining two is functional too, but I didn't achieved the integration of the code into the blocks. The results of the code for the two unfinished blocks should somehow scaled and moved to the correct place within the blocks.
Every solution is welcome! General optimization of my code is very desired (it is very likely there are more efficient and intuitive solutions)!
Thank you for your help and effort in advance!
