Can you legally sell Midjourney art?

Could you please clarify for me, is it legally permissible to sell artwork created using the Midjourney platform? I understand that copyright laws can be complex, and I want to ensure that I'm compliant with all relevant regulations if I decide to monetize any art pieces I generate through this tool. Additionally, would it be necessary to seek permission from the original artists whose styles may have influenced the final product, or is the creative output considered uniquely mine as the creator on Midjourney? Thank you for your guidance on this matter.
