Hello,

I'm sorry about your situation.

One law snippet I always remember and has helped me in a number of situations is something like “ambiguity in a contract automatically benefits the party that did not draft it”. Now, I got this from "The Big Bang Theory", but I have found it to be true based on my experience. I have cancelled at least 3 contracts with large corporations that were providing a bad service, without penalty.

In this case, since the artist drafted the contract, then those parts of the contract that seem vague, can be interpreted by you in such a fashion that benefits you. Within the law of course.

The Client shall pay the agreed upon amount of [redacted] € for the Character models/Game assets creation services as the fees of the Artist (Exact scope of work listed in Annexure A).

My interpretation of this is that you pay the artist for the assets. If the assets do not yet exist then you are not obligated to pay. I think this is pretty cut and dry.

I'm sure there are other ambiguous parts of your contract that you can interpret in a way that indicates a breach, and I personally would do so as this artist appears to be unprofessional based on what you have described.
