The pics is fine, just that it needs to be exposed longer. P10 is capable for it, and try taking the sky at dusk when it's bluish, this one's a little dull and too much of the sky. Keep it up
There's not enough color, it looks kinda bland. You used too little of the buildings at the bottom; either get rid of them totally, or try to apply the rule of thirds. You may have waited for a better, more dramatic sunset than a very boring one.
