Hi Stargazer,thanks a lot,i´m glad that you like my models,althought the pictures give the idea that my models are big,in fact they are a bit small,i use the 1-175 scale,this model for example,measures about 12,5 cm long and about 5 cm width,and sometimes it gives me a lot of work to build the interior of the cockpit since they are so small,about your question i usually use grey tons on my models,light,medium and dark greys,since i don´t use an airbrush,it is easyer if i paint them using just one colour,althought i have some models on witch i use two tons of grey,but this blueish ton that you see it´s because of the light when i take the photos,because unfortenately i´m not a very good photografer.
best regards
Pedro
