Though the MOC itself feels a tall and squished together. Is it minifig scale? If you're really trying to match the image you should note the patterns in the architecture and note important elements you need to copy in order for it to look like the source. You're missing a lower skull section thing between each of the pillars, so it doesn't match the pattern in the image. And also I would use a large inverted slope piece between the pillars
When building something like this, I would start off by designing a section of it first, like pic related. Starting from a element with pretty known sizes also helps you keep a consistent scale.
