Bonsai tree

Bougainvillea. Two things stand out; the flowers and the trunk. You might also notice the how small is the pot relatively to the tree. If the purpose of this tree is to show off its colors, then you would have to say it’s a screaming success. But what if you take away the flowers? Is it still a noteworthy bonsai? Or does that even matter?
In Japan flowering trees are often designed in ways that show off the flowers first and foremost. Normal bonsai guidelines do not always apply. In some cases where the flowers come and go almost overnight, the trees are moved front and center for that brief moment and then stuck in the back of the bench for the rest of the year. Bougainvilleas have an advantage; they can flower for months at a time.
I have been thinking about offering more critiques. It is a good way to learn and advance our skills and it doesn’t just have to be about me telling you what I think. You can write as much as you want in the comments, and going a step further, you could even offer your own bonsai for criticues.
My biggest question about this tree is the pot. I think a glazed pot would be better. It could also be a little wider and shallower. The depth of this pot takes a little away from the powerful girth of the trunk.
I like the root on the right, because it expands the base of the trunk and lends stability and balance. The other root in the center of the pot looks blueish and strange in the photo. Idealy there could be a root on the left side of the trunk which would counter balance the trees lean to the right. But ideal roots are hard to come by.
