Welcome to the forum, and nicely done!
What paints did you use, and can you tell us more about your technique?
If you're thinking about doing more in matte, may I suggest adding some washes to help pop the details, for example, adding a little burnt siena (or just a light brown), thinned down, in the recesses between the fingers, and on the face, at the neckline, etc. I do the same thing with my scale figures, to help accent the molded-on details. You can do the same on the uniform area, too, with the folds in the cloth, washing a little darker shade, to accent shadows.
Looking forward to seeing the rest of the vignette with his comrades!
Prost!
