I finished a few squads using the Kabal of Last Hatred color scheme. I like how they turned out but I'm struggling with a few details. I decided to try for a "ferric mud" base by using Stirland Mud with a heavy drybrush rust color followed by a light bone color. I'm happy with the result, but the model is very dark overall. I'm looking for tips on how to brighten it up. I'm looking for anything from whole new base scheme (not preferred), to different rim colors or grass tufts. I'm thinking of light brown grass and a much lighter rim color, but I'm pretty terrible at predicting how the colors will work off one another.
Second question is on the brass pods for the guns. I'm not completely sold on it but I can't think of anything better.
Sorry for the shoddy photography
