Really like design #1 the left and right vertical bars on the H almost look like two people exchanging an item sold between them. Perhaps this could be built upon so that they look more like people but the H form is retained with the item tag in the middle?
Nice job on #18! We like the idea of the platform under the H with the buyer/seller standing on it. Would like to see a horizontal version where the normal H is replaced with the platformed H with the people making an exchange of the sale item. I like the bevelled nature of the people and the platform. Perhaps try these changes with and without the gradient line through the text?
Great stuff! We're wondering, can you try a version of #27 with an adjustment to the gradient so that the top of the lower case L doesn't look so bright? Perhaps so that the color stays the same as the highest point on the other letters?
We appreciate your dedication and quick updates! Could you make a version of #44 with a small blue rectangular box (like a package) above the middle section of the H spanning nearly the entire crossbar but having whitespace between the left/right/bottom parts?
