So magic drawing for me..i really love this.. My impression is that it seem like the dragon is deep in the forest high above the ground at night and he is enlightened with a lights from som village and moon. Anyway all your gallery is very interesting, I like feeling aech your artwork gives.
Its quite a nice drawing. I see maybe the light in this is coming from the front-right from the viewer's perspective..actually that seems the sensible light placement in this scene..maybe to add more contrast you can or should just use more tonal contrast with darker pencils and maybe keeping the details as on the tree barks a little less so that the shadow and light contrast can be more vivid. I think the dragon just needs sharper outlines..But then I am not a trained sketch artist, its just my opinion out of my common sense.
Thank you so much for the advice It's a good idea to somewhat "blur" the background, and yes I also thought especially the head of the dragon could be some more sharp, but I just didn't know how, but I guess with a darker pencil would help!
