I like the process I see in these sketches. Also the final composition looks very cool, and I like the way the architecture looks although you may have a bit of trouble modeling (due to cylindrical basic shape, but that’s what gives it a special character). If it gets difficult, then try modeling one arc as a flat, then copying it around and rotating, which will give you more “octagonal” than round shape, but it will be easier to work with and you can dedicate this extra time to get the details right. Also, the position of camera seems a bit undefined – is it an intention to look from above, or from the eye-level (I assume from above).
