I like the overall color theme. The gray could use slight greenish shade to make it more cohesive with the other colors.

My main issues: 1. The 3D elements (passenger button, seat selection button) feel really out of place and outdated. I would use the flat language you use for your CTA buttons. 2. Don't use Lorem ipsum. There isn't a lot of text here, I'm sure you can figure a nice copy. 3. There is a lot of empty space at the bottom in the beginning. Screen looked unbalanced. See how big, popular apps do the onboarding process - Even if there is only one field to fill the screen never looks "empty". Typography is distributed more harmoniously across the screen. 4. While the design is not bad (though it needs polishing) - I struggle to understand HOW this app stands out among the competitors. Why would I use this app instead of Uber? What problem are you trying to solve that hasn't been addressed already with existing apps?
