PantherLehr,
looking good!
my only suggestions:
1) not certain from the photos, but i think i can see mold seams on a few of the figures.
be sure to scrape them w/ the back of your exacto (#11) blade, because the paint will 'highlight' them.
(if what i thought i saw was just the angle of the photo combined w/ the molded in detail, nevermind!)
2) i can't tell for sure from the photos if the figures have eyes.
if you omitted them because you did not want to try w/ a brush, heres a few things you can try:
a) sand the point of a stright pin down a bit creating a small flat circle. dip it in brown or blue paint wipe off the excess, and use it as a 'stamp'. test on scrap paper first to make sure size, shape, amount of paint and technique are what you want.
b) you can also make a 'brush' like the pin w. some stretched sprue. (groans from the audience! "NOT STRETCHED SPRUE" they chorus)
just stretch a pice and cut it w/ your hobby knife where the diameter looks good.
c) if you are feeling really ambitious, my buddy 'dots' the pupils black in the center of the eye w/ a straight pin and black paint.

on a completely unrelated front:
try to determine what you will do for a color/paint scheme before you start assembling.
i have tried to change horses midstream a few times myself and created a good deal of extra work.
whenever possible, figure out what you want to do and then work out the best way to do it before you start.
you may discover a 'better way' to use next time you are working,
but you will avoid some mischief. trust me, i learned the hard way!
other than that, i can't offer much in the area of 'improving'.
the airbrush should help, but that is a pretty impressive brush job!
congrats on getting one 'on the shelf' (well, it will be done soon, right?)
