The project I'm doing is "End of the Trail" Indian warrior on a horse with lance down. I'm not sure who designed the original, but got the pattern from Kirk Boleman. Anyway, it's about 180 pieces. It's about 2 foot in diameter, and most of the detail is with the horse and the rider.
I've done a couple of others before, a ship wheel and a tazmainian devil, which had fewer pieces but were also in circles. On both of them I started from the outside and worked in. On the ship wheel that approach worked out well. On the Tazmainian it was a struggle as I got to the inside with more detailed pieces.
This one is about the same size, but more than double the pieces.
Hope this additional information helps. I do need the advice of an expert.
Thanks for the comments so far, and any and all suggestions are greatly appreciated.
