It’s a good start and not a bad image….. However….. With the software that is available to us, many architecture students could do a similar job in the same amount of time or shorter and you would be entering into a crowded market. If you took this image into photoshop and improved it further, your work would stand out over others and give you a real shot at freelancing. Check out forbes massie on behance for good examples. Good luck with it! You are almost there!
