I would like to know where I stand now. Please let me know what I can improve on as I am new to all this. I can take it lol

This seems like a very odd composition having a blank canvass except for a plant/tree right behind the model.  I think the shot would be stronger without the tree or with it off to one side or the other.


I like the way you have captured her freckles and hair colour here.  Perhaps add a touch of light on the backdrop to soften the contrast?


I like this one - great natural expression from the model and pleasing composition.  The contrast seems a little low in this one though - is that intentional?


This is very good too.  Nice lighting to flatter the model.  Not so sure about the bright blue nails and white necklace though.


The hair/accent light is well done here and it gives a very clean, natural result.   Consider reducing the fill light a little to darken shadows and emphasize structure.


I would recommend less props (guitars, flowers, necklaces, chains) to let the focus really be on the model themselves, but that's a personal preference of mine. 

Having said that, I think the guitar works well in this shot:


I hope that's helpful.
