any feedback will be appreciated! thanks!!

My two cents:

If a school is asking for a portfolio, send one in. Not sending something as important as that should immediately disqualify you from admission.

I am assuming you are applying to transfer into an undergrad program. They should understand that you have not necessarily had top-notch design training and/or opportunities to create portfolio-worthy work, and that is OK. Do your best; the portfolio may consist of non-architecture design, so any drawings, sculpture or even paintings you have, consider them all.

As for the work you have shown, if that is what you have, throw it in. I would probably refrain from showing construction drawings in your portfolio, as they are not the best examples of design ability. Just make sure you show your work in a presentable manner: Photoshop out the sloppy backgrounds/redmarks, take good photographs with proper lighting and backdrop, play with contrast, etc.

Good luck!

SEARCH ISSUE or something for some portfolios and do a little work on your own like a simple design exercise and build some nice study models. look at the link below from MIT open Course which list the courses for alot of the architecture courses I linked the first studio work and assignment, try this out on your own do some reading and compare your work to the examples, look through a bunch of them and use the work to make a better portfolio or you can take foundation art courses such as drawing, 2d and 3d design and color theory.

Thanks Gary and beep!

So showing creativity should be my main goal in making a portfolio for transferring for undergrad?
