Petrolini Design

I like it, I can see the P and the D, I am not sure what the guys will say about the type and kerning.

Nice!

I like it! much nicer than your previous versions. I think you need a bigger gap between the two words though or try stacking one on top of the other, also the symbol for me is a bit big compared to the text. might be worth trying some different layouts with the symbol to the left and text to the right etc. good job!

Maybe, you can use other color for the letter "D"

I apologize if my critique is different from the positive comments above. I'm not a fan of the logo. To me the logo looks like a window in 3D perspective which distracts me from the letters that are part of the design. The additions to the sides of the square lead me away from the logo and seem unnecessary. I would also space the "petrolini" and "design" more so that they have some more breathing room. That being said, this revision is much better than the previous versions, and I think this approach is a better way path to follow for the future.
