Don't have the clouds fade out, simply make them get removed when: x < screen.width - cloud.width;

Also the cloud movement on the y-axis should be momentum based instead of constant. While tapping on the screen have a value... let's say, velocity, and set that value to 10(this of course would need to be a value that matches whatever scale you're using in your game). When not tapping on the screen have that velocity value lower constantly. Then, have something like: cloud.y += velocity;. This will make the cloud jump up, and then slowly begin to fall instead of instantly falling. Basically the movement of the cloud will look more natural, instead of moving like this /\/\/\.

I don't know if you're actually coding, or if it's purely GUI-based though.
