Put it to one side now m8 and call it done.
Start a new project and when you've finished that, look at the Ki again with fresh eyes.
If it still looks as good as you expected then stick a fork in it, if not, then get the crayons out again and play some more.
You've done a top job, you should be very pleased with the results.
There is a Ki-100 down at Hendon I didn't get pics of whilst I was there, (kids running around like their asses were on fire an all that), but I am going back again soon.
Let me know if this is of any interest to you
