Well, the first head has not that much details and im not an artist and i think that if i read some tutorials, i will be able to do it.

The second one has a transparent spot at the back of the head, fix it and it will be better.

First head: Add eyes or something and needs shading. Even for a first head it is too plain and easy.
4/10

Second Head: ... Fail Whale.
2/10

i think the first head is better than second head do you agree
