I really like this one! It seems they are taking a break from rallying the defenders of Minas Tirith to reflect on the situation, and perhaps send a silent prayer that Theoden arrive soon. Imrahil really does look like a representative of the Dunedain as they were at the beginning of the Age. The subtle detailing of his features does suggest Elven ancestry.
Wonderful!! Happy to find Imrahil, and such a fine looking one too. The only company to actually wear plate according to the book (if I remember correctly). Gondor's heavy cavalry. He has that true Numenorian air about him. The white of Gandalf really shines, almost angelic. Very expressive drawing. Love it!!
