The problem: Who doesn't want a nice clean arch? It lifts the eye area and makes everything look bigger and cleaner. That being said, more isn't always more. Basically, the "tadpole brow" starts as a ball in the front, and tapers to a string at the end. Not cute. You want a nice gradation from the front of the brow into the arch. Starting the arch closer to the front of the brow isn't going to make your arch seem higher — it's going to make your eyes seem crazy!
The fix: Put down your tweezers. You'll want the hairs to come back in the small space that has been overplucked. Find yourself a brow person to get you back on track. I'm not talking about your bikini waxer; I'm talking a person that specializes in brows. Consult, take his or her advice, and visit once a month until your brows grow back in. If they don't grow back, your new brow messiah can show you quick, natural-looking tips on filling in to get just the right slope.
