Lindsay,
I wish my first project looked that good. It's obvious you are learning from someone or paying attention to what your seeing.
You have nice deep impressions and a pretty straight pattern.
Now for the critique you want, the only thing I see is in the last picture. Have a well defined border and lean your tool away from the border when you get close to the edge so there are no tool marks past the border.
Other than that just practice, practice, practice................well you get the picture.
