Stalingrad rail yard

Stalingrad 1942, heavily damaged railyard

this is my first attempt at using a drawing tablet to produce an image. Really enjoyed using the software, although patience was required at times! . If anyone has any hints tips on using drawing tablets i'm open to any advice please!
