|Badly sited guns? Boggy ground behind a battery 1709|
So here are some examples of water on bases. In order to achieve similar effects ensure you have sealed the portion of base designated to be 'wet'. Do this by applying a layer of gloss varnish over it before doing anything else to it.
In the hot above, Swedish Dragoons splash through a particularly waterlogged portion of ground. The shot below shows the piece from a different angle.
Same piece again but from a nice angle showing how the positioning of the figures can draw your eye to the basing enhancing the overall effect.
Just a little piece of water can still provide an interesting touch. If it is a multi base unit make sure all of the bits of 'wet' join up to form something coherent and are not simply random patches of wet. That WOULD look odd!
Occasionally I'll have a few objects floating or half submerged in the water. Drums are good for this. You could try barrels, bodies, pieces of clothing or similar. It all adds to the interest of the piece.
