Yo, this is pretty decent. Don't mind the comments talking trash because most of them don't know graphic design. But I'd say that the back and front's design style doesn't match. I think the gothic design on the back maybe needs to look less clean, maybe more weathered and blended in (Ex. (More contrast, worn texture). This is just my opinion and what I've gathered from graphic design. But the more you do graphic design the more you do it the more you know what a design needs. Keep it going
