Hey, this one came out nicely. You really improved the shading since I last saw this pic. Though I never practice minimalism myself, this works cool on this pic. ( It helps that I really adore Rei, since she is the first character I drew when I "discovered" manga)
i am glad you made your lines darker, it's an improvement on the Un\tena pic's line work. Rei's face is also accurately drawn. I would make her darker shadows less saturated. It looks like she is standing outside on a very cold day from the light behind her. Anyways, Nice one.
