The first thing I noticed was that it is a lot bigger, than expected. So it could use shoulder straps, since it is quite annoying to carry it by hand, specially if it has something heavy inside. The side pocket hasn't found much use yet since the velcro can't hold anything up besides a few sheets of paper. Most stiches have threads hanging out (but that is more of an aesthetic problem rather than a practical one so doesn't really factor in). However, it is still in one piece and in working order. So while it could be improved upon, it does, what it is supposed to. I would recommend looking into Thomann keyboard bags. Seem to be working quite a bit better for me.
