It's looking better. Try giving us some other views and maybe a wireframe.
When translating from 2D to 3D, even when given an extremely accurate modelsheet, you have to take some creative liberties in order to make it look right, rather than following the proportions and measurements to the last millimeter. Especially when dealing with anime styles. So experiment with the proportions of the face, such as making the eyes a little larger, the head a little narrower, make the nose a part of the face itself rather than a separate shape, and maybe even play with the helmet a bit.
Another tip, give subdivision surfaces a shot with the eyes and face. It'll make it a lot smoother and more organic and natural looking, which helps a lot when making humans and other creatures.
Lastly, the materials and lighting. Part of the reason it doesn't look right is because you're going from cel-shaded flat coloring on the anime side to smooth lighting-based coloring on the 3D side. If you want it to look true to its original design, you'll have to eliminate the shading and (later when working in the scene editor) make sure the lighting works for the character. Attached are some materials (the basic trick is to have about 0.5 emissive and about 0.1-0.2 brilliance) that will imitate the two-tone look if you use a single infinite light source and the
inverted toon outline trick. Note that you'll have to play around with the materials a bit and the rendering times will increase tremendously if you want to use shadows with the toon outline. Also, the toon outline trick will make it harder to animate things, but may be worth the effort.
On a side note, modern-day 3D anime adaptations don't usually do cel-shading or toon outline anymore. A lot of times it's hand-painted textures with very light soft shading. You can google 3D anime and see a lot of examples to pick out, a lot of them can be imitated in Anim8or with a little effort. This is where that creative liberty, to do what makes it look right rather than exactly how the 2D version looks like, comes in as well.
