Commission: Sai

The first thing that caught my eye are the clouds. the variety of colours (which i might add, are really beautiful) makes them look almost real.
The tree, which is very detailed, even though it is done with simple round brushes (if i'm not mistaking), adds more detail to the background, and also balances out the background aswell: the sky has warm colours in it, the grass also, so the tree, breaks the repeating of warm colours.

Sai's pose is really well drawn,
The highlights make the clothes look more realistic and more eyepleasing, considering his outfit is black and his skin is very pale.

In summary, the entire picture is very eyecatching, the background is highly detailed, and the composition itself is very harmonious.
