Really like this visually. Would definitely like to see more of Gran ;)
I think you've made some really interesting choices for your characters so far, so it would be good to see them built on in future scenes and/or in reworking the current scenes.
e.g. there is erotic tension between the main character and Gran in the first scene, but then on the motorbike ride there is no mention of this.
e.g. the main character is the kind of person who punches a ripped tiger man in order to check whether he is dreaming or not (rather than just, for example, touching the tiger man's abs). What kind of person does this? What else would we see this character do? (to be clear, I am not saying this is a wrong choice, but if you've made that choice, what other choices follow from it?)
I look forward to seeing/reading more!
