hello I would like to know more about the software, to have more ideas for the icon.

It is basically a quickbooks for hedge funds.  A glorified accounting system.

It is also cloud based architechture.

Do you prefer a minimalistic design or a complex design?

Any particular color preference?

Any particular style?

Is meant to be for Android, iOS or Windows Phone?

From what i get the first image is a guide for the splash/start screen and shows the layout.

And the second one would be?

I have uploaded two new images of login screens for other applications.  This is a windows application.

I also uploaded the company logo.

By "Windows Application" do you intend a Windows 8 App or a regular Windows Desktop Software?

Can you guarantee payment?
