I'm writing a story, I wanna know If I'm wording my words correctly ?

Depends on what you're writing. If it's more like poetry, you have more freedom to use unusual or technically "wrong" wordings. Especially if you want to add impact or emphasis. If you're writing a story, you usually want the wordings to support the story, not raise attention in themselves. I don't think that "graphic thrill" is in anyway grammatically incorrect, but it's certainly unusual (the fact that you're asking this question shows that). Maybe "graphically thrilling" would work better if you just really like those two words. Otherwise, hit up the thesaurus. But for poetry purposes, I think it sounds fun and interesting :).
