It may be fairly common for photographers to use water the things like this; that’s ok because the main subject for me is the colour involved. An example of this is where you see the sharp reds throughout the fungus but in the water it’s all mixed and blended with soft colours.
Something that can be improved is how there no obvious centre of attention; witch can be fine for some images such as abstract but; most of the time hyper realism has a bold main subject to draw people in.
Because I like to leave things on a good note, I must say you have awesome camera control. All the extremely high contrast crisp parts are amazingly sharp!
