Great first assignment.
You’ve altered a “beast” to a “beauty” by focusing your attention through the use of tighter framing. While tighter framing isn’t always necessary to help isolate your main area of interest, in this case it helped because of the otherwise busy environment of the setting.
That being said, you didn’t over simplify the photograph which shows your bravery to include multiple objects and strong secondary elements. For instance, many photographers are drawn towards over simplification. In this case they may have focused on a crystal glass in front of the nice green wall. While, technically nothing is wrong with this idea, if the photographer meant to capture the atmosphere of the room, they would be compromising their image through oversimplification.
On the other hand, you’ve decided to keep in secondary elements such as the clock in the background, the walls, door frames, table cloths etc, to help provide context and create a strong tone.
The reason you were able to accomplish this so successfully is because you’ve organized and simplified in more creative ways. Most noticeably is your colour palette arrangement. You’ve limited your colour pallet to various gradients of greens, browns and whites. This helps give the image a cohesive look even though you’re framing is cramped with different objects, at different depths with different shapes. Knowing color theory and working with a color palette is a great way to help your photographs stand out. In fact, I would go as far to say it’s one of the most important, and most overlooked elements of photography.
