I don't often do studies at all in recent years, which I suppose is a great shame but I'm afraid it's a necessary side effect of me just drawing much less in general than I did some years ago. Occasionally, I do have my moments, though, and I was very happy with this study of Aragorn. Obviously there is a lot in his facial expression I didn't manage to convey in my drawing, but I feel I did alright. This was meant as a preparation for Wisteria; I can't tell whether it ended up helping or not xD
The purification phase at the start of each round of Opus can reoccur at later times during the round.
