When I was small, Umbreon was my favourite eeveelution. Now I like them all. ^^ I had sketched a pose almost like this a long time ago, and now I finally improved and colored it~
I'd say it depends a lot of the scanner. Some are just better than the others. However, a lot of it can be saved by editing the picture on computer. I usually use the "Levels" tool on Gimp for that.
