Really neat character concept! What Seeker specialities do you think you'd start with? Biology - Plants and Material Science - Bullets and Explosives both seem to fit. Maybe also Systens - Food Economics?
I really don't think Personal Touch is intended to work with Seeker - did you have something in mind for how you'd like to see it work?
Also Fifth, the Gardener doesn't seem to be the best shot (at most +2 attack) so maybe it would be helpful to pick up Improved Muzzle pretty soon.
