I don't know a THING about arabic, but I love typography and I have to say that I absolutely love the logos for the Al Qalam Library, the Raf Foundation and the Hotel Souq Waqif (those are my favorites, though the rest are so beautiful and visually appealing... you have a lot of talent!)
I really enjoy these logo designs. You have very insightful ideas, and they way you use Arabic calligraphy is quite beautiful. My particular favorites of this group are the Raf Foundations logo and the Al-Arabi Perfumes. Very smart and lovely in their simplicity, yet I know they are far more complex than they seem. They say a lot with very little, and in my opinion, this is the product of good design. Mumtaaz!
