Any help is appreciated

Didn't have much to do today so I decided to finally start trying to experiment with studio lighting for products. First I understand the backgrounds I used probably are not the key things to use for this but I made due with what I got. So any help would be appreciated.

The lighting looks good, maybe add another light to each side to kill some of the shadows.

But overall good work.

 

I think #3 is great with the exception of where the background meets the floor on the left.

 

Bought a manikin today to kind of play with portrait lighting and this is what I came up with.
