Art: The art is very unique and drawn by the author (SIU) himself at the start. Art is not its strong point at the start but bear with it as he gets way better as the story progressed (ongoing for almost 10 years now) and now he probably has an amazing team helping him out. Check out some new chapters if you're curious about the difference in the art now and then. The characters, shinsoo(kidna like energy in this story) , background scenes, fighting scenes, killer moves and techniques are all drawn to the highest level of detail and beauty nowadays.
Story: Not gonna go into the details to avoid spoilers but it's simply outstanding. Other reviews might have an outline of the story if you're interested. The pacing is slow at first and it might be confusing or boring depending on your taste, but absolutely stick with it. I'll just say that it just keeps getting better. Take your time, be patient and enjoy yourselves. There will be a moment when you start to go crazy and get obsessed with this story.
Character: The main character is the overpowered type. The destined one with unlimited talent and background. He's not the best character in the story and kinda typical for a shounen MC. .
The other characters are where it's at. So many characters who are all written to absolute perfection. Their relationships, family background, character designs (they look cool, their names sound cool, they act cool, etc...). Even minor characters usually show up or are involved in something later on. Everything and everyone seems to connect really well with everything else.
Overall, Tower of God/10. Definitely one of my favourites of all time and probably the best ongoing manga along with AOT
