Grafted Japanese Maple’s

[Canada Bonsai]

I am new to bonsai ... Two are Inaba Shidare and one is a Tamukeyama. My question is, would these be suitable for bonsai

Dissectum maples, and in particular weeping dissectum maples, are not best varieties of maple to learn with because they can be fairly uncooperative with the interventions we typically use for japanese maple development.

I attached some pictures of some pics I've saved over the years.

Off topic but good to know: the dissectums 'seiryu' and 'emerald lace' are becoming increasingly popular in Japan and many dedicated pre-bonsai growers have begun producing them on larger scales. They can be propagated by cuttings and sustained on their own roots, which is not the case for all maple dissectums.

I think weeping dissectum are difficult for the training, but are really beautiful when correctly trained. Having longer internodes and weeping branches they are better as big size bonsai, I have some in training (I will try to take some pics).

Seiryu is very similar to a normal japanese maple in the growing habit in my experience, I have two in trading stage, one is ready to be reduced (in this moment Is tall about 175 cm), the other Is a "puppy" but has a very good nebari so I decided tò give It a chance.....

Oh, I have a Coral Bark. So it won’t be good bonsai?

Just by way of information, here's my Coral bark maple before and after spring pruning today. I've been working on it for at least 15 years and you can see that the branches still leave a lot to be desired.
Also shows that the red bark is limited to the new shoots. looks impressive while it is overgrown but not much after trimming.
