Deary Deary!! I love how you are combining these nature-esque pictures with your absolutely beautiful Nishi. I love this. The grass looks a little too cookie cutter and her hair looks a little too tame at the top for it to be so wild and free toward the bottom -- but as an overal shot... you know I Love It. And You. ^_^ Always juu!!
Okay Okay... *pulls your hands from your hair* Well then lets fix it! Be Proactive! what are you doing different than what you used to do? I know that Nishi's hair has always been a difficult point for you, but perhaps you're overthinking it. The same way you did the grass, try that concept with her hair. Not as direct with sure solid and outlined lines, but, it may help with the texture and perspective.
