I think your own shade if a good tone for your features. I would suggest to add some highlights just to add some contrast. Make sure not to add too many as to overwhelm the color, instead try a partial to start with and refrain from going too pale of a blond. Try to stay within light golden blond tones. These tones will really draw attention to your beautiful green eyes and let you own color be used for depth and contrast.
Blond would be fun on you. Not only would it give you something new to love in the mirror, but your coloring can totally pull it off. Having lighter hair will bring out your eye color. Be prepared to have some serious fun playing with new makeup looks if you take the plunge!
