I think the river in the background is a bit high, and boats big comparing to the people on the left side of the river/street. But I like the blending of the water in the foreground.

i agree with erikuri

Cool!!

In addition to erikuri, you can ripple a bit the shadows in the bottom right corner, because they are in the water.

Did some tweaking (removed part of the source photo to connect the back water)... the ship is just going have to be a monster.. I tried to shrink it but it kept making the balance go wacky..

Thanks for all the help!!

Except for maybe the motorcycles on the right riding on the water (only noticable in high res) it's a pretty convincing blend, so good luck.

very nice blend author,looks very realistic...i agree with Jaw,in high resolution bike rides on the water...please try to fix that...best of luck
