The key to making a good rendering especially a 3D architectural rendering is that you need to focus on some items in the frame while the other items are slightly blurred. This gives the illusion of depth. Experiment and check what looks better. If there is a certain feature which you want to highlight ensure that you do that.
There is no such thing as perfect so why do we insist on making our 3D architectural renderings so? A little imperfection actually looks good and gives a realistic feel to the design. This does not mean crooked lines or a major flaw in the 3D rendering but a little ruffle in the rug or a crease in the curtains. Small imperfections like these make your design seem more relatable and realistic.
While most people who make architectural renderings base their design in sunlight, this might not be the best idea. It is good to explore different lighting options such as dusk or twilight to showcase what the design would look like during different times in the day. This will give the client a better idea about the design and can help showcase its beauty as well.
At times projects are being built in beautiful sites of rich natural settings but the architectural 3D rendering focuses on the home itself and not the surroundings. A good idea is to focus on these very surroundings which are a big attraction for a lot of people. Focusing on nature surrounding the structure is a good idea and something which will make people appreciate the project even more.
While a 3D architectural rendering is presented in the best lighting in the most agreeable weather conditions, it might be a great idea to imagine extreme weather conditions and render the project after it has withstood those conditions. This would prove to be an interesting depiction of what the house can withstand and what it would look like afterwards.
These little tips can boost your work up from good to great. Since there is a lot of competition in the architectural rendering world especially due to the cheap outsourcing options available, you need to grab every edge you can get! Thus, make sure you stay on top of your game and can implement new ideas to impress clients.
