Hi author ! Very nice picture
However, the bootle seems to be in levitation, try to make the shadow more black and less blurry

Good job of putting the animal in the water but you forgot to make the color of the bottle at the bottom the same brownish color as the water. I still see the blue reflections from the original source at the very bottom. I also think the bottom glass highlight needs to be darker to stop the bottle looking like it's floating. I think the harsh contrast between that bottom shadow and glass is causing the floating effect.

I did some changes at the bottom... thanks...

Congrats!

Congratulations George.
