Um, the speckled pot, although it is attractive, has some potential drainage issues that would be a deal breaker for me if I saw it for sale.
Extremely shallow pots are notorious for not draining well in the first place. They tend to drain very slowly because the water column they contain is shallow and doesn't "push" water out. Water tends to stand in the bottom of them-- if there aren't allowances for that tendency-like drain holes at the corners or ends, as well as the middle. Although this one have a number of drainage holes, they're not placed all that well. There are significant "dead spots" on the surface like at the lower left and upper left edges, as well as the lower right side. The indentations from the thumbprints here would tend to make that drainage problem worse, allowing small pools of water to form and stand--Bad news for roots. I'd see this one as a potential tree killer. Sorry.
I'm all for quirky handmade, but the bottoms of pots have to be level and pretty smooth universally. You can't ignore function. I'm no potter, but the long-time bonsai potter I know pretty well uses a slab roller, to take care of that issue. Those things are expensive, but there are probably cheaper alternatives to making level, even slabs for pot bottoms.
