As a cellist, it doesn’t quite sound like a cello – the notes are right, but there are qualitative factors that are lacking and the result sounds too sterile to my ear.
That said it’s a great synth approximation, and it’s equal to or better than a lot of MIDI cello patches I’ve heard.

Depending on what you’re doing it may be fine – I’d listen to https://www.ehx.com/blog/effectology-cello-concerto for yourself and decide if it’s suitable.
