I think it looks very good and you wouldn't need to do anything to it. If you want to do something, though, you might add a little blossom near the bow, under the top blossom to fill that part it a bit.
Good job.

Your roses look great, love your technique. I would tighten all the flowers up a bit. Move the top bud a little closer, add another leaf on the bottom right, and add a small bunch of filler flowers where the extra leaf will go, so the wires do not show.
Maybe add some kind of bow at the bottom of the flowers, also.

good job for a first try. The only things I would suggest:
Have your leaves at the "end" a little closer to the stem or otherwise hide them a bit.
Try to face or orient the roses in the same direction - the one on the top is facing the opposite direction from the others. Might just be a personal thing, but I try to have them all oriented somewhat in the same direction.
