Dgale,
nice tree.I like the current front the best.
problems?....the apex is getting a little thick.You might want to replace it with one of the many smaller branches up there.And, you've got a bit of a knob about half way up where the bar branches are.even more than the aesthetics of the bar branches themselves,the swelling they sometimes create is a good reason to avoid them.I'm sure these "faults" are less visible when the tree is in leaf.
All in all,really a nice looking bonsai.Some might say that it should be trained in a more tropical style.ie.wider than it is tall..but i like the route you have chosen for this tree.It looks more like a temperate deciduous tree to me which is fine.(again,too me
)
