lso, i again drag your attention, that things on the background should be brighter and undefinded. Things on foreground darken, detailed and contrasted. Look on your flowers. That is a thing i call "lack of detail" and "messy style". Also, the image hardly needs contrasted shading. Without shadows it looks flat and blocky. There are lack of shading on flower pots, on floor, on partitions. And also - never ever hurry when you draw. Some things on the image look so messy because you hurry to finish them. Believe my expirience - once you try to draw something faster than it comes good - you give yourself an permission to draw badly and quickie. Always think twice when you touch a image and jf some details need a 4 hours to give it a good look - give it 4 hours. There is no any solution to make a great art within small time. You will hate yourself for hurrying on drawing.
And also - there is totally no reason to draw water if you don't want to draw waves and water texture. Because if you dont draw it - it looks like a plain space and just a blue kind of floor.
Overall is a nice try, but you need far more practice and before starting from complex images you need learn a lot of things about shaping, shading and coloring. Visit youtube and search for "coloring tutorials", "perspective tutorials" etc. That things with proper practice will greatly improve your drawing skill within a month.
