An idea for october

so October is halloween... and i've been thinking of doing a piece about halloween... at the moment i'm leaning on doing this image i have in my head... it is of a lady with eight legs like a spider but using human legs... the word black widow comes to mind... and also maybe having the lady either cradling a guy's severed head or cradling a guy's head but he is already lifeless... hope i'm strong enough to get this done
