Please, begin your work in black & white ONLY. Do not submit an early draft in color or as a 3D render. If it is your intent to make a final draft in color or in 3D, please message me.
The reason is simple; most amateur designers try to gussy up a poor design with color and fancy renderings. This makes it more difficult to analyze a design. And, it wastes your time. A great design is a great design. A clean, naked design exposes all the weaknesses.
That being said, I most definitely want a Hollywood-style logo! But, making it color and giving it the illusion of brass or gold or metal is the second stage. You'll know you are on the right track because I'll message you. You'll get something like "I love your design! I gave it 4 stars! Please, do some kerning and make the following adjustments. Once we lock the B&W version, I'd love to see this in color!"
I'll communicate with you in detail, I promise.
But, if I'm quiet or simply reject a design it is because it is objectively amateurish. And, after having run a dozen contests on 99designs, I've learned the hard way that most amateurs will consume my time and take away from the stellar designs that simply need a tiny bit of art direction.
So, if I'm quiet...you know why. And if I'm messaging you frequently...you also know why! Best of luck!
