Hi Francisco,
This is a classic sculpt by Phil Walden who is a Planeteer and will hopefully chime in once he sees this post.
Typical of Phil's sculpting style he has posed the Lighthorseman in a casual stance rolling a cigarette up from his tobacco tin and with a cigarette paper dangling from his lip. I did this figure myself over 20 years ago and I'm surprised to see it still in circulation.
You've made a great start with the flesh tones and the slouch hat and I will be following your progress with interest. If you need any advice on uniform details, let me know.
