Looking good so far. Better than my first models.

And you can clearly see that you improved over your first batch.
Logan is the best of the bunch. But sadly the paint on his bolter arm looks to thick.
The same goes for the dreadnought. Some areas looking good but others have too much paint on them.
You should thin down your paints even more. Especially the lighter colors like bone or white can be to thick very quickly.
And you might try an edge highlighting with another lighter color than the one you used.
Some of the faces could use another wash. And either shade/wash the eyes stronger or paint them with a black dot. You don't need to paint the eyes white before as this often let the minis look crazed with wide eyes.
If you can recreate the face on logan for the other guys and add a black pupil you're good to go.
