This rustic table seems to be having a fight with the design of this area. The table isn't vintage looking, it's more mountain home rustic. I think it's the table that's the problem here. Can you return it for something a bit simple in line? Also, I think the vase is undersized for the niche and adding sticks to it is pretty generic. Look at this link as there are various pictures of niche decor. There's one with a very large and artfully shaped vase holding very zen looking greens. I have this same plant in my yard but don't know what it's called.

so far, i am thinking of moving the vase over, adding some type of sticks in it, stacking about 3 antique wooden boxes to the left with an antique item on top of the boxes. then, use a rustic planter on the table with a plant and a low basket to collect car keys and mail. i also thought of moving the chest a little more at an angle in the corner a bit. or use an antique camera on the boxes and a framed photo in front of the vase and boxes. ????????
