I agree, Marvin. This is very nice! Intriguing color combo and beautiful form. All are nice, but the other one that I partiularly like is your black seedling. Nice form and deep saturation
and I love those deep cobalt beards. If you could keep the color saturation and lighten those beards to a light blue---spectacular! I think I would opt for a cross with Obsidian to see what happened. Obsidian might be a good option for your dark plicatas too, since it has plicata heritage.
