You guys are very good, and I would point out flaws, but those don't matter because most people, don't look at them and it would be a waist of time.
That on 3d world is the most important.
But what I am really interested, is that you post lot's of renders and good quality. congratulations, but you should share some of your knwolodge, like making a small tutorial, on how is your workflow, and what is from 3d, and what it photoshop, that would be something good specially for Architectural students.
"It's now by knowing how to draw, that you become Leonardo Da Vinci"
"It's now by knowing how you lay down a brick, that you become Frank Gherry, Siza Vieira, Zaha Hadid, or a master architect"
IT's experiency of years that give you quality, like a good wine.
best regards
