| I think so if it's really good. Different medium is always a good thing. Show them a couple of drafting drawings. These could be free hand or autocad. If you don't have any don't worry. I would choose only about 2 or three of the water paintings. They tend to get repetitive. The people who view these things see hundreds of them so they don't have a lot of time. You really have to wow them. Pick maybe your best 10-15 drawings. no more than that.
Here's some options.
-drafted work
-free hand pencil
-water painting
-tapestry
-built models
-photos
They love to see models. Take pics of them and format it somehow on photoshop. Have a title also. I'm not talking models you buy in the store. These are abstract models made and created by you with some sort of theme. If you don't have any, once again don't worry.
I would only use maybe one or two of the tapestries. They have to be really good to show though. When the weather gets nice, try to go outside and draw a building. pay close attention to the shade on the side opposite of the sun, and the shadow casting on various parts of the building and on the ground.
Even photos you take of nature or buildings is good because it shows them you have an eye to be an architect. So main objective is to wow them. second is to make sure your porfolio is formated so it's easy to follow along. The third is to be as creative and unique as possible. Just be yourself. They are judging you not only on your talent but also on how your porfolio conveys your personality. |
