Joe, You and Timmo have set a really high standard for a Grenado build. Every time I see new pics I think what these guys are doing is amazing. At the same time, while still trying to get planks flat on bulkheads and filler blocks on my Grenado, I'm thinking, If only I had known that you also have to be an accomplished artist to do this stuff....
Sure, it can be plain vanilla without the additional detail you both have done (and surely hard enough at that), but seeing what it can look like requires an effort. When, as and if I get near the details your pics show, I'll go to a large art supply store in nearby Savannah, GA and describe the issues. If nothing else, it might be good for a chuckle. Meanwhile, the build goes on.
