deciding on layout... decisions and dilemmas

I really like the layout of the 2nd option that I have played round with. The only problem though is how to make it on 5 levels.
Here is the original shape that I am hoping to go for:

It has a nice flow like watercolour on paper and I would like to keep this shape.







I have now played around with the sizes:

Each space is a good size from what I can see to house each studio in.









Just realised that the joins between each space is too small... there needs to be enough space for stairs and 2way flows of people.

Now it has completely disjointed the spaces and it is not what I want it to be >:(
