Step 5: Sculpting and the ornaments
I have used some spare pieces of styrene for the ornaments. Cut the horns to shape with a utility knife, file them to shape and glue them onto the helmet. Do the same with the five gems on the top brace. Shape them the same way as the helmet: putty , file/sand, putty, file/sand and repeat. Make sure to use enough putty around the horns, because they are likely to break off, if the helmet falls on the floor. Sand your helmet until you have an nice surface.
Once totally convinced with the surface (in my case regarding the time left to finish the helmet), cut some cable and glue it to each side of the upper brace and on the top and bottom lid of the base ring.
That's all for the helmet's shape, you can proceed to the finish. Prepare the helmet for coloring with a white primer.
