The gig looks good. The profile seems okay too.
While the images do look good and realistic (the 2nd one I think looks more realistic than the others?), I’m not sure if “hyper-realistic” would apply to all of them (eg. the 3rd). But they’re realistic & well drawn. The first image (aquaman) looks realistic but it may look more realistic from a distance (where the paint strokes blended in more).
An issue is probably that you might get in trouble for putting copyrighted characters/people (with IP rights) in the example images. eg. if you don’t own the rights or have permission from the rights holder to use aquaman/the person who plays him (and any other characters you use) in your advertisements you could get in copyright/IP trouble as well a possibly get your Fiverr account in trouble.
Nice profile - maybe hire a designer and get some custom gig images 
but definitely not bad!
