They're not bad, but also they don't have the super quality or realism that we're used to in CollectA, Safari, etc. I've seen just the lynx, a year ago or so, for sale in a local stationery. The sculpt is more simple than for the Mojo lynx, but it have the advantage of having ear tufts. Paintjob of course is better to customize.
Sirenia, I don't would have high expetances with crocodile. It's an Orinoco crocodile just because it's marketed as it, but I doubt a lot that it have the features that distinguish Orinoco for other crocs. Is just a generic croc marketed as orinoco, as many other brands do generic crocs not markete to species that we usually tend to assignate to Nile crocodile by default.
