Hi Mitsutaka
Its a lovely figure, well painted , well done. May I just add something, I see you are quite fast and productive painter, I too used to be like his, as I would imagine many others on here. But this only leads to a full display cabinet, filled very quickly. Try slowing down a bit and learning from what you are painting, textures, materials, flesh colours and tones dry, wet or snowy conditions, ground work of the area the figure is taken from, its all relevant to the finished figure, this will then bring out your attention to detail, just push yourself a little more on each figure..... your quality will improve no end.
