made the sponson darker because it's an overhang and thus shaded
it is not only the color the problem, it is that when you colored it , you loose some lines, they have completely disapeared,
- Refer to the original drawing or to good photographic references
for "shading" you have to think in 3D, thus the different parts of the sponson sould have different color variations
to do the work you have fixed you need good informations and ........... time.
Never think; i
just have to do........
I do not criticize what you do, i am just stating that sometimes, the work needed for doing something is much more time consuming
than what we have think at the beginning
