As a special treat for Prime members we have a full guide that details how to convert GiM-57 Saint Louis into his equestrian statue at the front of the Sacré-Cœur in Paris.
You can build the same statue by following the steps or apply the techniques to your own models and projects, especially the patina effect, which is super-simple and looks very effective.
