It definately needs at least a border-I would add a narrow border first (say, 1/1/2 ") in maybe the darkest color on that green print(can't tell if it is black or dark green), then a wider border (maybe 4") in a red print. Looks nice! I think since it is with Xmas fabs, maybe make it either a small table topper or wall quilt.
Be sure to use your rotary cutter and ruler to trim around the edges to make them even before sewing any border.
