That's a good looking balcony The vase looks great! Maybe you could try to give either the railing or the table a different colour, cause right now it is hard to see, where the railing ends and the table starts. And I'd also suggest you to add a shadow for the table on the floor. Good luck

That looks a lot better already! Good changes! Just two more small things: The shadow looks good, but it would look more convincing, if you'd make it more black and lower the opacity. Not much, cause it's obviously a bright sunny day, just a bit. And if you'd flip the flowers in the vase, you'll have the same light source. They get the light more or less from the upper left side now and the table gets the light from the lower right side, so if you'd flip the flowers, you'll have the same light source Good luck again!

nice idea, however you have the candle burning and it is soooo bright yet it appears to be day time and no clouds around, the candle would hardly be visible i thought.
