Some German troops advancing through the countryside in a rainy day during WWII, unknown unit or front.
So I tried to scan my drawings at a higher resolution (600 dpi vs 200 dpi). It makes the files huge and takes quite some time to scan, but the outcome is actually worth.
Trying to draw vegetation, basic landscapes and weather effects as you can see. Hopefully, I will be be making more backgrounds for my future drawings.
Small edits and re-uploaded the file in JPEG.
