Reuploaded with some revisions, I added a boat too. 

 Yeah that's because I drawn the water and looked ugly so I resized it to half size, not intended at all.

 Oh now I see that the tail is just messed up with the animation... I will fix it once I have enough time.

Thanks for the tips :D

 First of all thanks for your critique, I'm still new at this and every comment is welcome.

This was one of my early isometric works, and I noticed some things wrong too so I reuploaded this with some improvements.
