Tucano Corporations

A lit bit of background could help us understand what the symbol represents.

That being said, this is not a good logo.

First, the yellow has to go. Never have a bright color, let alone yellow, on a white background. You're just ripping our eyes out =)

The second biggest problem is to me the composition (we really need a thumb for it!!) It's uneven and unbalanced. The main mass of the logo is on the left.

Lastly, the font is really boring. You must take some time to search the web for cool, professional looking fonts. You can start looking here www.losttype.com and here www.fontsquirrel.com. Check out www.fontsinuse.com, you won't be able to download them for free, but it's a good way to learn about typography. Also, when you find a font you like but you don't know how it's called, head to www.typophile.com/typeid. Pros will ID the font in a matter of minutes. Really useful.

While looking for fonts on the internet, you may wind up on DaFont. I recommend that you stay away from it. There are a few descent fonts there, but only a few, hidden behind a multitude of terrible fantasy types that you should only see on a birthday party invitation for a 5 years old =)

Good luck!
