Can a freelance artist in a S-Corp biz report a loss for hrs worked with no pay?

I'm a freelance artist and have structured my business as a S-Corporation for tax benefits. Is it possible to report the hours I worked last year on projects, but did not get paid for as a business loss? For example you create a lot of art to be sold, but have fluctuations in the year where you're selling art generating income and periods where you're not selling anything generating no income. Can you report that time you invested working as a nominal fee per hr. to offset actual taxable income you received? Any insight would be appreciated.
