I applied your modifications and submitted the new concepts #40 #41 #42 #43 . The design looks very good and can be used in black and white or mono-color version too (think about letterhead or stationery)
I created a new design adding a tower and a hill, you can see the new previews with different color combinations #48 #49 #51 #52 #53 #54 . Let me know if you have in mind other changes.
I submitted the new designs applying your modifications, entries #71 #72 #73 #74, I hope you would like the changes, I tried with two different fonts for the tagline and I toned down the white figures.
Thanks . For #74 can you keep the bottom font but just enlarge it. Still a little small. Also, put the figures back to the white, that's not what we wanted toned down, its the stars...there are too many :)
