>>1869125You are NOT doing something wrong. Looks good so far.
That being said: I DO have some suggestions to make it look a bit better:
* For the hair ends: While you CAN have them as they are, try playing with "V" shapes to give it different depth. IF you are unsure of what I mean, I or someone else can post an example for you (Think of the Asuka bangs from a month past, if you have been lurking that long...)
* The red line in the image (ignore it says "fixme" name - that's my "go-to name so I don't have a bajillion rogue fix images laying about) - the red line shows how you could bend the lines and still retain the shaping of the hair to be more in line with the one like it on the other side. It also make sit look less like a "puff" in her hair.
Hope this helps...
