Reddit mentions of Fine Ballast Shaker, Gray Blend/57.7 cu. in.

This is solid tabletop quality paintjobs, the sort of army I most enjoy playing against. If you do the rest of the army to this quality, you'll be fine. Your photography sucks, but it's good enough that I can see you've got solid brush control, have done washes and highlights, have picked out sufficient detail, just solid work all around.

The only issue I have is the lack of basing. For miniatures like these, I'd really recommend doing a simple basing scheme like a ballast mix painted in earth tones. It's very plain, generic but doesn't distract and gives a miniature a finished look, and is very cheap for doing large armies. Here's an example.

You'll need:

• Fine ballast
  
• Medium ballast
  
• Coarse ballast.
  
• PVA Glue (i.e Elmer's white glue)
  
  Here's how you do it:
  
  
  

1. Mix equal parts of all three ballasts in a small container so that you have a wide dispersion of different sized grains. About one teaspoon of each type should be plenty for a unit of 10 troops. I usually use a plastic blister from a miniature, roughly 1.5" wide x 2" long x .5" deep, but you can also cut a plastic cup or aluminum can down to 3/4" high and that also works great. You don't want to use a really big container or all the fine ballast will quickly settle to the bottom and you want to be able to easily stir it back up to a mixed consistency.
   
   
2. After you've fixed the model to the base but before you prime it, use a cheap brush to paint the surface of the base with white glue.
   
   
3. Dip the miniature into the container so it's submerged in the ballast mix up to it's ankles. You can just kind of sweep the mini through the mix then shake it a little, and you'll end up with a nice mix of ballast glued to the surface. Wash out the brush throughly when you're done, but not in your water pot. Wash it under a tap.
   
   
4. Let the glue dry, then make a mix of 1 part glue to 1 part water, so a very thinned glue and, using the same brush, go over all the ballast again. This will help seal it to the base.
   
   
5. Prime the mini and paint it as usual.
   
   
6. To paint the base is very simple. You really only need a dark brown and a light brown. Paint all of the ballast with the dark brown, then lightly drybrush it with the lighter brown. If you want to be a little fancier, pick up a set of the Reaper Soil Colors Triad, and paint the entire base Muddy Soil, then heavily drybrush with Basic Dirt, then lightly drybrush with Brown Sand.
   
   
7. Paint the sides of the base with any basic Black.
   
   You can add some Army Painter Tufts or the occasional piece of talus for larger bases to give them some variety.
   
   It will really improve the model, and is much less work than trying to go back and base the model after you've painted it.
