Greetings!
The logo I am about to create is going to take into consideration every demand you have set.
I like to think of modern as an abstract way of expression with minimal details that can beautify the whole concept, while keeping it noticeable and easy-to-understand. The context (digital graphics company) is an area of marketing where this kind of design is not only applicable, but also much in request, since it coexists well with the company's up-to-date character.
Attractiveness, on the other hand, is always in the eye of the beholder. I personally believe that most minimal projects are attractive, on their own, for most people, but I'd like to ensure that your taste is going to be expresses through this project. So, I'd like to ask you if there are any special demands about the part of the design, that will make sure that you will not dislike the result.
Please, let me know if you have any questions that weren't covered, or if you are interested.
