Responsive Landing Page

In my free time, I started to work on various design concepts to train my UI skills. This is a landing page for a feature/product, called Custom App.

I was always afraid of the bright colors and very often people would tease me: "But this isn't blue, it's gray!". I guess new color trends in design, wider thinking (and, maybe, even better weather conditions in my current location) is helping me to be more bold and courageous in palette selections :)
