design - Help with a second menu - Admin Page

I'm doing this second menu for a web site, but they told me is too much " old style" and they don't like the disposition of icon... Any suggest for me please? Thank you

• The second menu is only in that section " flow designer/builder "


• in the grid it will be possible to draw flows, so I need the space of the menu to make visible, after the user choses icon, other configuration options as text input etc


• No much colors available...(I 'have already use them)

THANKS!!
