Hi friends, I have been commissioned to create an image for a mural for a museum exhibition that is of a 1900s general store. I've drawn it out, but my understanding of perspective isn't concrete yet (though I just signed up for Marshall Vandruff's perspective course which I am SUPER excited for. Could someone please help me understand where I am going wrong in this drawing? The composition has already been approved by the client so I can't change that, but I need to make sure the drawing is solid because it will be blown up to a 12ftx12ft(ish) wall. Thank you for your help!
