It's certainly a very bold framing of an individual, standing as such on that rampart.
I feel the use of contrasting detail, focused foreground & less distinct distant detail, gives a great sense of scale, while also not overly taxing your efforts as an artist.
It's certainly a clever choice, in a smartly composed piece.
Honestly I also adore you shadow work, especially the way it's cast on the banner, which it's self is detailed in it's thread and pattern.
This actually reminds me of the style and detail of the Vampire faction from the "Magic the Gathering" set "Ixalan."
Thank you for making this.
