I do not know exactly should I write about your photoshop skills or your photographic skills here, as I also checked out your tutorial, where I could see the original image. The final image is a nice one, it doesn't have much impact, cause such shots had been done so many times before, but it is always good to exercise. While I like the over saturated orange/red tint, I am getting distracted by the burnt out yellow on the left side (that was later darkened? and looks desaturated now, which doesn't make much sense with the over saturated orange). Also the bubbles on the top (specially top right) are so weakly defined you could easily removed them or enhanced them a bit more.
The original image shows your weakest point - lighting. The reflection was probably hardest to remove, next time use a big sheet of black paper with a hole cut for the lens to remove the reflection. Also you can use some tin foil under the water tank (plus on the side - if you have light coming just from one side) to reflect light back to the subject, that should give you more bubble definition.
Also now I can see that the weakly defined drops in the final image are the ones that seem to be on the glass itself from previous shots, maybe using a rug between each shot would help with that
Overall it is a nice try on this ever popular subject, and it shows you can frame and use your shutter speeds correctly. And that you are trying to give this shot a bit more meaning (vide heart). I would say - keep trying and exercising, that is what makes us good photographers.
