Hi Guz
The angle of the building looks good. try the following:
1. try to use a sqare base, see how it look.
#39 look like a penis.
2. There is not need to make "E obviou"s. E/H/C can be abstract.
3. forcus on the building it self. using diffrent approach to make the "H", dots. vertical lines, horizontal lines, outlines. we need to see more approaches..
4. what the logo would like if there is there is three building?
we are very clsoe to what we want.. thanks
