general
Large open area as you walk in, large entry into dining room (assuming that is what is to the right), but with stairs coming down like this, a little more cozy of an entrance into the study (assuming that is what is to the left). Problem is, still feel like we're walking into the staircase. If you make this space wider, then it is a huge unused area that will feel vacant and museum like.
Super tall still, but the angle of the roof brings in a little more cozy feeling. Fireplace wall needs more windows to open it up, but consider the family room may not need the same roof line as the upstairs... maybe it can be a little lower so it isn't a full 2 stories, yet, where the upper level looks out into the room... it may be a little taller to accommodate a view out the back.
