I love it! Congrats on pushing through until the end! I think that is often the hardest thing to do - you get through your inspiration and then you almost want to give up, and it's sheer will power to see it through no matter what.

The island on the right helps to balance out the work, I think. One recommendation (not for this, but in the future) is to think about more foreground to add even more dimension. In this case, maybe some leaves or twigs in front on the right to add even more balance.
