Too much white on tips "cuts off" your nailbeds and makes your fingers look stubby (and less natural).
At the other end of the spectrum, instead of thick tips, some girls prefer "Discrete French Manicures." These have very thin tips. You can take this idea even further towards minimalism and paint them even thinner than in the above pic so they are barely noticeable. The subtle style is nice but it is more likely to get chipped.
