How Would I Look with This Hairstyle(pics)?

Well i've been wanting to get a new hairstyle for months and i've found the perfect hairstyle for me and I like how it looks on rihanna(even though I hate her) but the hairstyle is fabulous. But Im not sure if I could fit the hairstyle cause my face is round.
