Before you get too invested in this tree, I think you should consider that Juniperus chinensis 'Torulosa' is almost never used for bonsai. Personally, I don't have any prejudice against it, and I have several enormous ones that I am trying to develop, but it will probably mean grafting them over to something else like 'Shimpaku'. When something like this isn't used, there usually is a good reason, and in this case, it is probably the coarseness of the foliage and its lack of 'twigginess' or difficulty in ramification. Just for the hell of it, I just googled Juniperus Torulosa Bonsai in the images section and came up with only one decent looking bonsai as far as I could tell, but the picture is so small, I can't even tell for sure if it really is 'Torulosa'.
You may want to just use this for practice, they are tough as nails, but I don't think that's such as good idea either since we have a way of getting attached to our efforts. There are several very common species that are suitable for bonsai that would make better choices: 'San Jose', J. prostrata, 'Sea Green', 'Lemon Hill', J. sargentii, J. procumbens 'Nana', and anything else that you can find that small scale like foliage as opposed to spiky sharp foliage, although some of these are used too such as 'San Jose', 'Foemina', 'Ridgida'. Ones to stay away from (that are very common) are Pfitzeriana (and its cultivars), tamariscifolia (YUCK!), J. conferta (nice trunks but difficult), J. squamata and its cultviars, most ground cover types unless you can find a very old one with a good trunk, variegated ones, stiff upright ones like J. communis 'Compressa'. If you ever find any young 'Shimpaku', snap them up.
