colorwork help

[boyforpele13]

i am working on a colorwork sock, the one on the cover of this book here: http://www.rustlingleafpress.com/
i am having several problems... the fit is one of them, but it mostly fits me, but i think resolving the more pressing problem will resolve that too...
it's a toe-up sock and i have completed the foot. that green pattern on the instep stitches, it just doesn't look like that on mine. i mean, the sts are in the right place, but the green sts are really obscured and very small and the fabic almost resembles ribbing... how do i fix this? i am using the two-handed technique from the Philosopher's Wool video, and weaving either every other or every 2 sts depending on the row... what do i do?

thanks!
