Greetings Bob, , rather late to to your conversion to 4BO. :smiling3::nerd:. Sorry for this, have no idea why I missed such an important build. Looks really good. :thumb2::thumb2::thumb2::thumb2::thumb2:.
Hopefully you are going to do a pinwash to pick out the lines between various parts, like around the hatches etc.
Congratulations on the colour, If you want to do high lights, one way of seeing where the light falls is to shine a light from the angle of the sun on to the model, then spray the lighter shade where its picked out.
Say after me 4BO rule 4BO Rule 4BO Rule., see its not hard.:nerd:
