Heya ashy2ivy, welcome to ThePhotoForum!
These are some really wonderful black&whites of your little girl, I am happy for you (and us, mind) that bribing her into posing for you with M&Ms helped ... now it's just a pity your photos show in all these different sizes. I can go put the missing spaces between each of them but can't do much about their size...
What do you use as your studio and you light?
