Hey ARC,
Most of your photos are showing up as broken links; if you fix that I'd love to see some of your older work. As it stands, I can only comment on the Starship mods. The addition of the Jedi symbol to the starfighter is pretty cool. I also like where the gunship is going, but it looks like you used a brush on it...I would have recommended an airbrush, or as a cheaper alternative, some good spraypaint that's designed for use on plastics. It will give you a nice, smooth finish.
I'd also hit the black with a dullcote to make it look more realistic. The Monkey-Lizard applique looks cool, but needs some careful trimming, as a few areas clearly show where it was cut out. I'd also invest in some quality clear sticker paper, as it looks like you may have gone the regular paper route. Those few tweaks will bring this baby home nicely.
