Ah, thanks for the tag @Leo in N E Illinois I had missed the new photo posting.
I would agree that your front is the one with the small styro fleck. You do need to get more movement into those branches, and if you don't want to do it with thicker wire, then you'll have to do it by cutbacks. If you are planning on a repot this spring, then I would not cut any more off of it until it recovers. I would suggest getting it into a better soil, that looks pretty organic, although I don't know maybe your climate is very dry and you need lots of moisture? You'll also want to recut some of your wounds where you cut large parts off, cut them flush to the trunk and then seal them. If you have a concave cutter, that makes it easier as the wound will heal flusher to the trunk. Crabapples are loath to ramify, you must make them do it. @Martin Sweeney gave me a good tutorial on crabapples long ago that I've used to develop mine. I'm attaching the text here.
If you want to totally remove a branch or cut one back hard, it should be done in late fall (after leaf drop) or late winter (before bud swelling) being sure to apply medicated wound sealant. Doing so during or after bud swell can often result in either water sprouts or die-back. You should prune last year's shoots at bud swell.
Crabs are difficult to give exact training advice on because they can behave very differently, not just between varieties, but also from plant to plant and even year to year. I recommend experimenting with different techniques and making very good observations and taking good notes.
If you remove the flowers, shoot growth is usually very strong. (If new growth is not strong, only perform light maintenance.) Keep watering and fertilizing on the lighter side during the spring flush if flowers are removed. On extremely strong or early shoots, tip the new shoot once 2 or 3 nodes have formed to shorten the internodes. To induce or strengthen backbudding, once a shoot has reached 1", cut it back to just 1 leaf. Any other shoots should be tipped when they are at least 1" long. There are 2 caveats to soft pruning crabs. 1) DO NOT soft prune shoots once they are over 2" long. Otherwise you run the risk of getting a branch that does not flower. 2) DO NOT cut too many (say more than 1/3) of the new shoots in one sitting, but spread it out over 2 or 3 weeks. (I did that one year. Because I removed flowers and didn't control the water and fert., the plant rocketted away. I trimmed the new shoots all at once, and the plant collapsed/went into shock. Gladly it survived, but I set it back several years.)
New shoots can be wired in early summer when they are semi-hard. I cut new shoots back (where needed) in late summer here, but that might be something you need to leave until spring. The trick to creating convincing branches on a crab (as with most bonsai) is to grow them very slowly, maybe 1" per year.
JudyB,
Are you sure that was me? I certainly don't remember it, but I am getting old!
