I agree with previous commenters.

For printing purposes, work on a black and white design. Black on white and vis versa. Perhaps have one symbol outlined and the other filled.

Final stages, you would want to stick to no more than 4 colours. Then design the look on a black and white background. Stay away from similar shades of colour. Think about people with visual colour deficiency.

Think of it like a tatoo or car decal or window decal. It show look good on all surfaces.

Generally, without the background… See More

I don't want to be pesky, but i found this on wikipedia: Roc (from Persian رخ Rokh or Rukh) is an enormous legendary bird of prey. Is this correct or?

Try experimenting with colors and combine them,then try it on different backgrounds like what Davor said. Also, use colors that could give some appeal and reflection to your company's mission.

I read through all the comments here and I simply have to say that Davor's suggestion on playing with thickness is absolutely your best way to make this friendly and easy to understand by anyone's eyes. The way you write in this language should tell where to add thickness and where is should thin. I challenge you to grab a paint brush, black paint, and white copy paper and just draw this exact logo out with accurate, but quick strokes. Try it a few times and show us your favorite one. I think you'll… See More

much better than before
but it's still missing something
read this articel for your logo referene

Idea is good. But: how logo looks in B/W? how logo looks on different color backgrounds? This eye(dot): i'd like eye contour similar to real eye. Eyebrows: straighter lines without this endings. Lines: i'll would play with thickness. So the overall look of logo gives brush drawn feeling.  

cool project but imho i need to be able to read your language to give proper advice. to me who do not understand your language, it only is a drawing that makes no sense besides looking a bit like a face. i did study design and in my opinion i would concentrate on an image first, and the letters last. this is more calligraphy than a logotipe. images usually are more impacting for the brain. but again, i dont think i know enough of your language to have any opinion on this subject   have fun  

that Shayan is for the copyright things ahahahahahahaha

I'm going to be honest and say I don't like it. But I'm from a part of the world with a very different tradition within design. A tradition that would not put text infront of the logo so both become harder to read, shadow would probably not ever be used and the font used for the face has both hard square and round edges and have too much white empty space. I however have close to no idea how it would work in Iran - it could be perfect there
