Its good to see something from Fate/Stay night again.
I have to point out though that Sabers face just looks weird for some reason. The more i look at it, the more it just seems the features aren't right. All the characters look like statues in those positions too. XD The background (mountains) is nice but it seems like something that was whipped up fairly quickly. Some more detail would have been good. It also looks like their house is situated in the middle of nowhere seeing there's nothing else around except distant mountains.
On another note, the sky is nice. It's pretty simple, but it has a nice feel to it. The way you added to light to it was good also. It's quite a fun scene you have shown and i still think you did a pretty good job nonetheless!
