can any one advise me on ways to improve my mountain maple

Can we see a picture from the other side, too?

One thing comes to my mind immediately: Four trunks is not a felicitous number for a bonsai. Maybe one of them could go -- the smallest one? (or are there 5 trunks?) Need to see the back.

Otherwise, from this one view, you have a nice bit of material to work with.

It would improve if you gave it to me!
I'm looking at your tree: The far right trunk, to the right of the clump, crosses the rear trunk. This is distracting. In addition this trunk is very straight and doesn't help the whole composition. The main tree looks good straight, but the supporting family of trunks need movement (or bends).

I would curve the small right trunk outward to (not cross the back trunk) the right. This will open up the inside of the clump more, which will also invite the viewer into the clump. A branck bending clamp might do well with this. I have never used one, but would try it, if it was my tree.
I don't know how to do virtual painting yet. I hope I explained myself well enough. A lovely clump which will only get better with age! Thank you for sharing it. Regards, Todd

Kingbean--nice multi-trunk maple you've got there

I would start simply by removing the moss around the base of the tree to expose the nebari and the nice flare the trunk has low down. This will establish the interface between soil and tree and make for a more powerful image.

Todd's point about the trunk on the far right is valid and there's an easier way to do it than he suggests--wedge a chopstick between the tree to its left so that it pushes the trunk to the right enough to be able to see the rear tree from the front. Use a chunk of rubber on each end of the chopstick so you don't mar the bark of both trunks. You may need to leave it in place a couple of growing seasons but it will be far less invasive than trunk jacks and wire, etc.

I count 5 trunks and even if there are 4, we are not in Japan. A good multi-trunk maple is hard to come by and not worth changing just because of a number--sorry Jim. If the trunks were aligned in a square plan, then I'd say get rid of one of them...Otherwise, let it be
