Is it permissible to work as a sales rep in this case?

Assalamu Alikoum

I work as a sales representative (I get a commission for each deal closed) for a marketing agency and this agency promotes projects and each project is different, some projects have 2D drawings or 3D or sometimes there are projects with no drawings, etc…

My question is if I get clients for this marketing agency, is the money earned from the commission halal or haram or do I bear a sin if I do so or I have no direct relationship with them?
