The interface you're using looks like Blender to me. If it is, are there any tutorials that you recommend? The only ones I can find are for the Mac version which doesn't help me since all the hotkeys are mapped to different buttons apparently.
As far as the 3D modeling itself goes, I like it. The proportions so far seem correct with her face, and it looks like it's got this cel-shading style you'd see in anime fighters goin' on it (dunno if that was intentional or not). Can't really judge too much off of what you have but I am looking forward to seeing more of it as you progress.
