Thank you for sending the variations - we really like the circuit concept. However, we feel the tree looks a little sick now (like all the leaves fell off)... where the tree in #34 looked very healthy... could you investigate keeping the circuit concept, but making the tree look a little more "alive"?... perhaps adding the solid tree trunk from #34 (we like the tree trunk design), with the circuits coming out the top... just an idea - but please feel free to they anything else you think will work too - we have high hopes for this design..
Also - we really liked the filled cross in #34... perhaps incorporating this filled cross with #64 would also help.
We also liked the contrast (shade of green) used in #34... but we are not sure about yellow for the cross- it looks nice, but could you investiage other colors too?
