Very nice work, that red and black shield in the top picture is especially good.
I agree with jamesmanto, some static grass (and/or maybe a bit of dry brushed highlighting) on the base would finish them off nicely.
Also, have you considered a matt finish? I know it's a matter (no pun intended) of personal taste but I think a shiny finish can detract from the details in the painting. It also helps reduce the glare in photos (shield on right most knight in the top pic) and lets you display your work at it's best.
Keep on going, you're building up a good collection there.
