this is the original scan
what did i do?
i extend the scan and redid the sky
the clouds are handmade by my extremely old-fashioned ball mouse and smudge tools. thanks to my sister luciferheart for teaching me how to do clouds via mouse.
the next thing i put is a gradient and soft-light it to give a more colorful shades of the sky.
that's all i could describe. :)
