i've been working in advertising/publishing industry for 15 years. to be honest, creative market is majorly affected by this pandemic. client's are cutting their expenses to sustain in the business and the first thing they will cut is on the 'marketing budget' - which is advertising/publishing materials and etc.

having said that, it is all depends how good you are. pick up other creative skills, beside illustration - that will help you in the long run.

wish you all the best
