It has been forever since i drew ben-ben like really been a while

Iv Been Trying to do Digital Sketches to Digital Line Art Then to Color

Im used to Sketching but Doing Line Art i really need to make more of an effort to make nice ones like others out there :)

As for digital coloring/painting i need to learn to do more details or textures [ which i kinda yet to learn or figure out ]

Any Words of wisdom anyone ?
