I began to make head. Rate on 10-point scale. Whether to make a set for it, or to finish up and sell?

You need lots more shading.

6/10 as it is right now.

And the lines need to be a bit cleaner and straight. so yeah bout 6/10

Huh, nice head, but you need work harder with torso and hands.

Sup
[Wip] is not an approved tag for the art board. As your art is a texture I have added the [Tex] tag for you. Please be mindful of tags in the future.
Thanks

Thanks for the comments, this is first version of the head, I'll add a shadow. Overlord, this torso - one of my terrible sets (it does't apply to the head.). Solax, I just did not know what it means to tag [TEX] ,next time will add.
