You're a little low on workers, as evidenced by the fact that the war front is completely unroaded. You're using some unimproved tiles, too, though you've managed to make up for it by using coast tiles, which produce adequate food (w/ harbor) and good commerce. An early palace jump might have been profitable, but you placed the forbidden palace well so that's not a big issue. Your forces are arrayed a bit haphazardly; it would be better to form more coherent stacks. One major problem I see is Tamuin. It's a core city but only at pop 3! You should've cut down some of the forests and done some irrigation to let it grow.
Now, a few good things. You've gotten over "mine green, irrigate brown". It took me a while to get over that, but you've done it and I'm sure your city development is the better for it. Like I said earlier, your fp was well placed. You seem well in control.
Lastly, I would recommend that you not play with accelerated production on. It gets you into bad habits. If you can research techs in 4 turns at only 50% science, I'm sure you're competent enough to not use it.
