AT, nice work! Another tip, and I'll say I've used it with varying success, but when painting using masks, or stencils, put the mask or stencil on the subject, rub the edges down well with a toothpick, or Q-tip, and then give it a couple of light coats of the underlying paint color. That helps seal the edges to prevent bleed-under. Once that's dried, shoot your final color on it and let that set a bit. Go over the edges of the stencil with a sharp Xacto blade before removing the stencil.
As I've said, I've used that process successfully with paint, but it doesn't work well (for me, anyway) trying to seal mask edges around windows (using clear, it bleeds under, creating a crazed window effect).
But yeah, nice work on the invasion stripes, they were hand painted in a hurry.
