Which sketch is better?

[cantmakeme]

I just want to be able to tell if I have improved

Both really good. Second looks like a more developed style so would hazard a guess that it is more recent? They look like different people have drawn them though as the pencil marks are so different!

Thanks. There are actually three!

But you were right!

I should've said I'd attached three drawings

They are all good but I more like the second one. It is more detailed and developed.

I like the middle one the most.

Definitely the middle one

The middle one is the most life-like.

The last one is a bit stylised.

The first one lacks something.

Middle best

Middle best by far though the third is good too. The first one looks to have been done but a much less advanced sketcher, especially the top eye where the shape looks wrong.

2nd one
