It think it looks very good for a first effort. The only problem I see is that the relief carving behind the rear thimble and tang seems to have edges that are a little too rounded, at least for this stage in the carving. The moulding lines look sharp so I am not sure why the other carving is rounded off. Did you take sandpaper to the relief carvings behind the tang and rear pipe?
As Rich said, a little modeling could help, but don't overdo it. My problem is that I get too ambitious for my skills. I think nice sharp, crisp carving with just a couple of incised embellishments is just fine for this stage in your carving.
I like the drawing behind the cheek piece. Just make sure your lines are nice and sharp, just as sharp as your tools, so that you have good lines to follow.
