Welcome to Android Central! It's a matter of opinion, of course. But don't tell this to us--give Google the feedback. With Camera open, swipe in from the left, then tap the gear icon at the lower right, then Help & Feedback. Then tap Feedback at the upper right, and tell Google what you think.
Is it the icon you don't like, or the fact that there's a big blank space around it? If the latter, then remember that that's there only if you're set to 4:3. If you change the ratio to 16:9, that big blank area will go away, and you'll see the camera shutter icon superimposed on right side of the actual camera image.
