OK, not really that exciting, but I have added the second level of gray (No. 2) to the pants. This is the time to begin picking out the wrinkles. Study some photos to get an idea of how light and shade play off the wrinkles of pants. Some miniatures lines are good at sculpting realistic wrinkles, others are not- so you may need to highlight based on the sculpt and not based on real life. All in all, it's your personal preference on how to paint the wrinkles.
The shirt also has had its next level painted with No. 4. I have painted a hint of wood grain on the stock of the BAR using No. 2. Gunstocks vary in color, so experiment with your grays to find what suits you.
