Mike,
looking good. a few points meant only as constructive criticism.
it looks like there might be camo overspray on the right front tire of the 251.
also the track on the 251 looks like it is defying gravity in the front between the
sprocket and the roadwheel.
on the Panther
(yes, Panther, Woodbeck3 - Panther! :-) )
the tracks look too tight.
are those indy links, or the vinyl 'rubber band' tracks?
Panther tracks were known for the sag,
and typically they touched down around the middle of the 2nd road wheel
(from the front) and laid across the tops of the rest and then rose up
over the idler.
if they are individual links, it would be a major repair
(break, make angled sections, re affix)
if they are rubber band style, you may be able to use thread or fish line to
cinch them down to the road wheels.
the Panther camo looks great as does the weathering & the figures.
the 251 looks a little uniform on the color.
it may be the picture, or it might benefit from a wash or dry brushing.
your post says these are 'early builds' so you might already know all this.
but just in case.
(you did ask for help to improve. so please do not take offense.
overall, they look good. quite good)
:-)
keep posting!
