I think this piece really gives Sweden an air of a strong-willed, quiet man- especially the facial features; it appears like he was a serious, calm person at the World Meeting (something, as we all know, hard to achieve). The dark coat, broach, and the scarf? really added to his appearance, though if it was at the meeting, I would've expected his to be in a suit, so maybe it took place at a negotiation instead? But then that should be in a suit too, so maybe this is just how Sweden dresses.
The background felt like as if he was in the World Meeting- well, it looked like his arm was on a surface of some sort, and something of a curtain to his back. Maybe it was during a negotiation- in the case, that will work too.
It is also possible that he is, in fact, standing up, from a viewer's perspective. I see his other arm, the one that's not leaning against the golden structure, almost as if it was in his pocket.
I do not know what the curtain-like item is doing behind Sweden, so perhaps you should clarify that a bit. Also, when you look closely, the coat doesn't appear to match the way Sweden's head is facing if I propose that he is sitting down. I think the body is tilted too much. It looks like as if he wanted to get up and leave the moment the event he was attending is done.
Also, in accordance to the anime, I believe his glasses was rectangular, not round. This can work if it's another of his glasses or something, but I'm looking from canon, so as much as I love the Harry Potter styled glasses, it's not accurate.
I also looked very closely at the arm- while the left arm was leaning on the golden surface, making me not able to see the width of his arm, the right one seemed a bit too small for someone his stature. That could have worked for any other Nordics except Denmark, but remember that Sweden's size is pretty much the same as Russia. His coat arm, in addition to containing just his arm, must also adapt to the cold in Northern Europe.
Same thing with his body- inside the coat contains layers of clothing- making his body seem larger. I think you need to work on that more.
In general, I love the picture, and I especially loved his nose and dark coat. I also believe you did his hair perfectly, so major points on that. Keep working on art, and I am sure you will improve as time goes. Thank you for receiving me.
I love this! I love how you have it gives off the aura of his personality and the style is just amazing. The blending of how the light would naturally hit his face is wonderful and overall this is a very well done piece.
