It looked ok. There is an overriding principle with casting and that is to provide a release. This means instead of having straight sides the mould form should be made so there is a slight angle, maybe only one degree. An example of this is a bucket with a slight conical form. Of course a sand mould doesn’t need this requirement because the sand can be easily removed. Polystyrene is also easily removed. Providing a release from the mould form is actually more important than the application of a release agent like oil.
There’s nothing worse than not being able to separate the casting from the mould.
