Yes, my email is in my profile. BTW, I don't like how the grade down to the yard on the outside flows. I just did that without knowing what you final space measurements were and I believe it goes too wide. I just posted it to give you an idea of an alternate way to get to the yard at a less steep grade.
FWIW, I used to work out designs with graph paper, tracing paper and one of those template rulers designed specifically for that and I much prefer the software approach.
