Great work on the contrasting and perspective. Credit for adding various shapes of animals and people, and for the torches and the distribution on the light of the castle. Everything is looking pretty good, but next time think about the visual quality of what you put in the middle of a drawing. It confuses my eyes (and focus) a little to see the top steps of the stairs being so wobbly-ish.
Other than that, I get a feeling of something grand (maybe hysterically grand ) countered by what lies in the forest surrounding this architecutal masterpeice.
Thank you for bringing it all the way by adding a logo to the red banners as well... Gives a sense of completedness to the sphere and general understanding of the drawing ^^
