Today i took few hours to work on the cannon, i must say i am thrilled with the result
For the wood i have followed a tutorial on youtbe, just search as : painting an imperial cannon.
Very good, even thou i did not use quite the same colors of paints.
Today i think i have really a great chance to work on my dry brush technique, the wood and the iron were done entirely with dry brush
Wood
Base: flat black
Lights vallejo german camo black/brown + vallejo natural woodgrain + beige brown+ a dab of mahogany brown
Add more beige brown and a drop of vallejo natural woodgrain and dry brush it in several times until you are happy with the tone of brown for the wood.
The secret is to thin down, almkst to a wash consistency.
For the edges of the wood i added a last final dab of vallejo panzer aces german winter white (offwhite).
I have applied on the edges, the idea is to highlight edges but create the effect of wear and tear, so apply it in an irregular pattern.
