As I said, I like your catapult! But while it looks cool on the title, the side view (ingame view) looks quite odd. One can't see that these strings are supposed to be from the bow of the ballista. Additionally, for my liking the wheels are too small and the construction looks too clumsy (the wood is too "fat"). After all, I opt for the schleich catapult because it's functioning is more obvious and simple to see from the ingame view, plus it has this toy-like feel to it (actually that one seems to be a toy): not having a too clumsy construction and a big moving part. The thing to wind up can stay in the schleich construction if it looks good since in both constructions, it would be used to get the basket down.
