New updates on 19/3/2017:1) Improved ground lighting below Luna2) Added glow to one more crystal3) Minor improvement to mane extensionsNew updates on 22/3/2017:1) Luna re-shaded with improved anatomy2) More detailed caveAt first, the idea of Luna with a background that has a silhouette of her head struck my mind. Therefore, I tried adding trees in a forested environment at first to mimic her head with the branches. But it didn't turn out well, so I tried using a different approach, a cave. To my surprise, it looks much better and more beautiful I suppose! I'm so glad this wonderful piece is finally done! I think the crystals add a really nice touch to the overall feel of the artwork. Furthermore, the night environment also feels very cool, as it's located high up in the Frozen North. The cave is also a very quiet place, hence giving a sense of peace and tranquil.Now, Luna is standing there reminiscing about her past and how she could help to improve the lives of the ponies under her charge.This piece took significantly long to complete, with about over 20 hours combined over several days. Here are some WIP images to show you the progression since the beginning:Anyway, I hope you like this! The program used is only Photoshop CC 2015.
