You did a much better job with the background in this picture than with Alysangela's picture. As for Kiirn: wow. Great attention to detail with the pattern on his shield, and I'm just loving the overall result. This guy's perfect!
Valid points. I viewed this slightly differently. The buckler is worn on his arm because, as the pose suggests, he isn’t in combat so therefore he has his buckler in a carry position. Plus, anyone and everyone should carry a knife (in a culture such as the one I assume this character belongs in); nothing here suggests he uses it at the same time as the buckler.
The image says to me, that ‘Kiirn’ is in a relaxed, almost cocky stance, probably boasting about his skills with his blades. This composition works for me with a little imagination and self-inserted backstory.
