I wasn't happy with how the cannon looked as I mentioned in my post yesterday and have decided to add a coat of Army Painter's 'Dark Tone'. This was in response to AD's comment on the last post, informing me the metal should be very dark (almost black). I have to admit, I went off a mixture of sources for the painting style, primarily from the way other bloggers have painted similar models or those models on the Perry site which seem to vary from a very bright silver to almost black (or silver with 'black lining').
I think it looks quite good after being 'dipped'. I used a brush to paint the dip onto the metal areas and removed any that settled on the lighter wooden areas. This was to darken the silver and add a black line around the outside of it. It will be varnished again once the model has dried (around 24 hours after application). I think it looks quite good like it is now (I couldn't bare another re-paint!) and will look even better once based and the crew have been added.
Once again, please leave your thoughts and feelings as a comment on this post as they are invaluable to the project, other gamers and myself.
