The tree looks good. However I am concerned about this last one in the shallow pot. I would imagine that you had to take off quit a bit of the root ball. To be honest, I am not sure that the tree can survive on this little rootage. Well, not all at once anyway. There is more to root pruning than just sawing off the bottom 30-%50 of the root ball. Actually, many times, a saw is not even necessary. Just patience and a chop stick. You need to just keep going all the way around the root ball over and over again gently scraping and pulling the roots off of the ball to untangle them. I use a saw only on the most extreme, pot bound, cemented like root balls
The best advice I can offer is when and if you find a bonsai club, I would inquire about root pruning practices. Many times, a tree cannot go into a bonsai pot out of the nursery can. It is usually moderately root pruned, then put into a grow pot. Grow pot refers to the purpose. Then when the tree has filled the grow pot with fibrous roots and recovered well. This usually takes about 2-3 years, then it can go into it's first bonsai pot. Sometimes, if the nursery can the tree is in is small enough and the tree healthy enough, it can go into a bonsai pot.
All in all, the tree looks good though. However, if in about 6-8 weeks, the foliage on the entire tree turns a different color or becomes more pale, you will knwo that the tree is not going to make it. I wish you luck. It is a nice starter tree.
