I started Tie assembly from the cockpit. After its assembly, I airbrushed as a base color Neutral Grey (XF-53), followed by Badab Black wash (Citadel) and highlights with Astronomican Grey (Citadel). When everything was dry I sealed it with Satin Varnish Vallejo.
Inside the fuselage was sprayed with Neutral Grey (XF-53)
I also quickly assembled tower / stand for placing the TIE. For now it looks quite plain, but I plan to change it a bit.
More fun with Tie Interceptor soon.
