Thanks guys! Exhaust area will receive additional treatmant a bit later on, so that pic is really an "in progress" one.
Bernd - Problem with Zvezda is that so far, they released only Su-33 (in use only with Russian Navy) and Su-27SM (in use only with Russian AF and with some mods can be built into Indonesian one). It is by far, the best looking and accurate Flanker in 1:72 but requires some work if you wanna backdate it to the basic Su-27S or Su-27P version. I hope Zvezda will soon release other variants as the kit is designed to enable multiple versions by just switching certain parts.
