FEELING STUCK.....

I'm in the middle of a design crisis..I'm stuck: I've spent the whole afternoon trying to change the central area of my detail design, I've come up with 15 different options and I don't like any of them. I don't know if I'm a perfectionist, or if I've run out of ideas or if my design scheme is wrong all together or if it is a combination of all these things.
It's strange because when I was working on my planting design project with Andrew Wilson I experimented with circular shapes and curves and I realized that once you start to use them you have to apply them to the whole design. I was told they are tricky and anything different from them looks out of place.
But now that I'm using squared geometric shapes for St. Leonard's I'm feeling trapped too: anything looking different is in contrast and must be redesign.
The area where I have my curved walls must be redesign from scratch again and the options I have designed this afternoon are all based on the geometric shapes I have used for my terraced gardens at the top of the park.
At the moment I feel that the different areas of the park are disjointed and the whole scheme needs to be redesigned because I don't like it... hope I'll get some help on Friday with Julia!
