Dear steemians, on this occasion I am pleased to inform you that I am participating in an initiative born from the need to obtain a logo to help the sister of my friend @artzolino, I thank you in advance for the confidence in the talent of this community.
Regarding the design, I wanted to take into consideration all the features that are mentioned in the post in order to achieve a logo as similar as possible to the one described. Here are the resulting variants:
Design #1:
Design #2:
As you can see in the previous designs we used a range of blue colors, the letter B was placed in three dimensions and finally the word Legal in one of the designs in the form of a shadow, the font used is modern type. I hope these designs are to the liking of all of you...
