The content of this looks great but the art.. I dono its putting me off. To my completely uneducated and untrained eye it looks like it's because there are no shadows and everything is uniformly lit. But its also gone for colour palette and underlying style that is semi-realistic. I think you either need to go all in on comic style if you cant do shadows (im guessing no shadows = much quicker time to render) or take more time to add the extra layers of detail that make the pictures less jarring to the eye.
