I am sorry if I have join late. All design elements are there and it need some final adjustments.
Here is my suggestions, if you don’t mind.
- Related to color, you have picked dark blue, shades of blue and white color. It is balanced well. Some of the color connotations of blue are loyalty, security, conservatism, tranquility, coldness, sadness. Indeed it look to me little cold and boring. What do you think of third color. It could be discrete add. Few details nothing much if you prefer that way. It should be some light color picked carefully depending on feel you are trying to provoke.(light green,orange, light brown,yellow) Try experimenting a bit. In that way you could distract those cold feelings. If not, maybe could try with purple instead of blue which provokes creativity, mystery, royalty, mysticism, rarity.
- Related to fonts I see to many different fonts or its variations or too many different sizes. Either way it looks messy even you have done good color balance. Try to simplify it. You have chosen Sans fonts because of logo font I suppose. It not convinced me that these two fonts are balanced or united. If I were you I would try to add more prestige and royalty. So I would suggest Sans Serif fonts. In that way you could add contrast too and emphasize logo name. Either way I suggest you pick another uniting factor.
- Other impressions are that it is well organized and one general suggestion that you try to rid of every design element that is not needed (like that big shade wheel representing Shares I suppose) that way it would look more simple and clean .
I hope it could help.
