Wow. This piece of art is amazing. The technique used for the scenery could have been done slightly better but in context it is just right as it is the background and Shadow is the 'center piece' as such. I love how the Shadow symbol is on the flag too, that really stood out for me. The way you have portrayed Shadow himself is epic, I feel that this picture shows that Shadow has just won a battle and he is proud and is a savior in a way. The effect of how the light is shining on him too just tops it off. This piece is certainly very original and it stands out from everything else.
Congratulations and a very well done piece.
