Dark Saber Fate Stay Night

Anatomy- Looks great :}, nothing wrong or out of proportion.

Shading - The metal parts of the armor(and the boots could use more lighter and dark shades to make it more shiny like metal, try using more hard edges on the metals. The shading for the skin is good too, i can tell it's skin and not super shiny. The clothes is also good, but the folds are a bit awkward. Overall, remember that different objects reflect light differently, metal reflects a lot of light, and is very smooth, so add more lighter shades, and since you'll be adding more lighter shades make it proportional and add more darker shades also. The blending shading style is good for things that are not smooth, like clothes in skin, but for the metals try another style, maybe blend less for the metals (while still adding lighting shades and darker shades).

Details- Amazing :}, the boot shoe things, are really awesome, and the gauntlets.

Fabric fold- That one big fabric fold is really awkward, it looks like it's on a table edge because it's so linear. I don't see where the ends of that fold is being made from? The knees aren't bending out to make any creases. For a more flowing skirt(or dress??) don't put linear folds, make them start towards her waist and make curved folds(like the skirt folds you already have there but more loose) and go out to the direction you want them to go, all folds going to a general area. If there is metal on top of the skirt, follow the same rule, but keep one starting point, and one general direction out.

I hope this helps! It's rather hard to explain it in words, it's easy to show through pictures ^^''.
