I coloured-up the hydra scene for the Heroes of Hellas RPG.
Just used the original pencils without any modifications (despite the temptation to fix MANY things...).
Once again I have fully painted the sky in my ongoing efforts to master painting. No imported textures here.
I added atmospheric effects, blur, etc. All by hand. There is a stone texture used on the rocks, though, which is my one cheat.
Everything done in Sketchbook Mobile, on my phone, with my finger.
Here is a higher-res version of the image. I hope you like...
