A lovely image. I really like how the clouds below and the curvature of the horizon suggest that he is flying at an extremely high altitude, probably at least fifteen kilometres above sea level, and how his speed is so clearly yet simply shown with that shock cone around his nose and the condensation trails on his wings.
I REALLY like this. The angle's great, the water and the clouds look really nice, the whole picture has excellent shading, and this picture expertly captures Latio's jet-like appearance and serious nature in contrast to Latias, who is also drawn very well by you. 5/5, and favorited.
