I finally managed to paint and base a second artillery piece for my Renaissance "Impetus" Heavy Artillery unit (see below). A classic from the Games Workshop 'Empire' fantasy range, but a good enough match to the Renaissance for me. The 'new' gun is the left hand side, a dirtier bronze than the pristine one on the right.
It was great fun painting theses fellows as the old 'Empire' figures are full of character (see below). I used the standard three tone technique: Base, shade and highlight from a mixture of my end of life Games Workshop Citadel paint collection, their Vallejo replacements and the very useful Anita Acrylics colours.
Multiple models in a battery or formation just reinforces how difficult these things would be to move and helps the player refrain from fantastic wheels of more than 45 degrees.
I just hope these chaps do me proud on the battlefield, well painted troops have a tendency to rout going by my experience ;)
