Some people would object to 'making him seem'. If he seems, he 'should' either 'seem [adjective]', 'seem like [Noun Phrase]', or 'seem to be [adj. or NP]' [e.g. 'seem happy/seem like a professional' etc.] In all these cases, the underlying verb is 'he was...'.
In your sentence 'it seems as though ...' would avoid this objection - but not everyone would object anyway.
