It could benefit a little by thinning the lineweights. Otherwise it's really good and unique, especially so with the layouts, not the traditional white space/organized approach

Yep - work on lineweights, maybe a little more initial process stuff. You're well on your way.

I think PDFs are tricky online, never know if that stupid feature "Enhance Thin lines" is on.  I know in Issuu I had to change some of my drawings as jpg instead of pdfs since the lines all looked thick even if they were different line weights in illustrator. 

I turned off that option and still they are rather thick.

Thanks guys...I will work on my lineweights

Also I am adding a couple more renderings and I will post the updated one later

The following is not related to the architectural design, which looks interesting, but only the portfolio. 1 Less is more (page layout) 2. Let it breathe 3. I am not finding an unifying idea for the organization and proportions.

Thanks for your input Bay Bee.

For the first point, do you mean putting less drawing onto a page?

Secondly, I am not quite understand what do you mean by let it breathe. Do you mean having more white space between drawings?

And for the third comment, I tried to have the same order of drawing for each project. I guess that's not too obvious.

Also I am editing of PS right now, and I want to have some feedback as well. Would you guys mind to take a look?

Thanks!
