Bump Map Level Test (Feedback Needed)

Hello, I was working on some bump maps test for unity to see how lightning can effect the looks, and was wondering if i could get some feed back at what i have so far.

Here are some photo of what they look like :

Thank you for reading this post and for any input if given ^^

It is amazing just need something
It is to dark a little light

Thank you for your comment and what would that be ?

Make sure you have your lights render settings set to imprtant. It looks a little too dark to bring out the bump mapping.
