Looks good enough, given the quality of the pictures. Try using less white in the background. The camera has a difficult time with dark subjects in front of a bright white backdrop. Medium blue, gray, even black will work better.
Als, especially since this was a presentation, before dofoing a lot of work on the groundwork, paint or stain your base then wrap the edges in masking tape. You have some very unsightly glue stains pouruing down the side, particularly in the last picture.
