Hello there! From a written content standpoint, your gig is severely lacking - you have no story, no explanation at all in your gig text. Why would a seller want/need your illustrations? You need to speak to that - maybe for a menu or brochure, or maybe for a large graphic on the side of a food truck.
Also, it looks like all of your examples use the same style / color palette - if this gig is just for illustrations done in that style, great! If you’re offering various styles via this gig, however, you should probably update the gig images to reflect that.
Thank you very much for your advice ) I will take this into account.
