Hmm, this question is a hard one. I think it's Yes and No. Animation requires a lot of observation, study and practice (sometimes i need get up of my chair and make some poses in front of the mirror ^^). After you understand the principles deal with de software is the easiest part. Speaking in animation, is not a matter of easy or hard, is more about effort \o\! About 3D modeling, texture, illumination and stuff i personally consider very hard ;o (i have difficulties in it). ^^
This looks very pretty an I do like the shininess of it. However, I do notice an issue with her skirt clipping through her thigh on her right side. This is probably caused by some sort of wind effect on her clothing pieces and the cloth ignoring the skin. Other than that, this seems a solid piece (considering how much vocaloid work you have to compete with).
Yeah, i notice that too in render result =/ (after long 4 hours of render x_x), i think it was because i worked on this animation through different versions of the software between my notebook and desktop, well i was really focused in walking animation cycle on this work, that was my first animation in life ;D ! And I know I need to improve a lot about a lot of things, so... Thank You VERY Much for your feedback ^^.
