You may hate me for this, but I don’t really like any of them (for being the logo representing the whole project.) Something more dynamic and flowing could be in place.
However, in light that it may be used for the film itself (as a logo emblem upon the cars and motorcycles… I think…) then it is fitting. My votes are for 2, 5, and 7.
Well, I mean, 2 and 5 are good, they work. If you want a sharp, bisymmetrical logo, these can work. In fact, I may get used to them and learn to like them more. But perhaps you could consider going with a different approach to the logo: presenting three highly contrasting logos that represent the Morevna Project perfectly in each of their own, respected ways, but are all different.
Some very good logos are:
Borders (a book store) borders.com/online/store/Home
Wycliffe (Bible translators) wycliffe.org/
And some logo design tips: thelogofactory.com/logo_design.html
(I don’t necessarily support all their advice, haven’t read it for a while, but it’s a source to check.)
Is this going to be the logo for the Morevna Project (used for promotion/the website/absolutely everything representing the Morevna Project,) or for Marya Morevna’s motorcade (in the film)?
I believe logo design is awesome, difficult to get right, and a VERY important and core tool for a business, group, or project.
God bless and best wishes,
P.S. If you decide to keep with the current logo design and it becomes the official logo, I will stand behind you. If not, I offer my hands and mind to assist you in the pursuit of an excellent logo: in suggestions, critique, and hands-on work if needed.
