I'm really happy with the way my Star Destroyer turned out, but I think it needs a little something to bring out the details. For the high spots I intend to to do some drybrushing but before I do it I need to bring out the low spots/shadows. I usually use washes, but with the size of this ship I wonder if ground up pastel chalks might be better? I've never actually used them, so I thought I'd get some imput from someone that has. I'm mainly looking to bring out the scribed panel lines, but was wondering....would that look to overdone in this scale? Remember, the model is 31 inches long with a LOT of panel lines. Any help would be appreciated.
