Twilight Sitting Adorably

The other thing i’ve thought of doing to participate in the brony community, inspired by ask-thecrusaders’s amazingly show-accurate pictures. i want to see how close i could get to that.
before i try to make original show-accurate images, i decided to start with just tracing from the show. looked at a lot of tutorials, downloaded Inkscape, and did this
my first vector. traced in Inkscape.
the source image and color key i used are included in the .svg

my biggest problem is incredible indecisiveness, so any suggestions for what images from the show to vector next would be appreciated.
