We need to know more than just "it's a statue that freezes things around it." What story are you going to tell - How The Foundation found it, Who or what created it and why, did someone use it to some end? (These are not all questions that must be answered, these are some possible narrative hooks.) You need something that differentiates this as an SCP, instead of just an Anomalous Item.
I also recommend reading several (at least 10-20) of the top-rated SCPs from the last several months, and avoid reading series 1 SCPs for inspiration. Many series 1 SCPs would not last a day under current SCP standards, and a few are only still around because of their history with the wiki itself. (This does not apply to all series 1 SCPs, as you can see I mentioned 093 earlier, but many of these were written before the wiki's style had really been cemented.)
multiple instances of SCP-457 and SCP-310 were needed to recontain it.
Having your SCP's containment be reliant on reference to other SCPs - especially Series 1 SCPs - is not recommended. Also, I disagree with the Keter classification. The anomaly itself, the statue, is not actively trying to escape, is it? It should be Safe, all you need to do is keep it in a (heated) box and you'll be safe from it. The classification is about how difficult it is to contain, not how dangerous it is.
The object, while important, is not actually the main focus of the SCP. A good story, a compelling narrative, something that makes the reader feel something - that is the goal of an SCP article. What feeling do you want to evoke from the reader? Horror? Empathy? Sadness? You need to create a narrative around this object and its effects.
I am not saying this to discourage you, I just want you to understand the amount of effort that goes into creating a successful SCP.
If you can revise this idea with a story that you want to tell, we will be able to give you much more meaningful and constructive critique.
