A Review of Logo Design for CloudWorks by Dragos Ungur

nice work ! i like the nr 3 and 4, but i suggest to make the nr 4 like nr 3 (clounds with wheels).

nr 1 is to simple and the wheel is like the sun ... and nr 2 is to retro :)

nr 3 and 4 are very cool, but try to combine them for a uniq logo.
