Shadowdove, I'd agree that there are plenty of unbalanced homebrew creations.
I'd say the two presented here aren't the best balanced-the first was a bit too strong, the second a bit too weak.
But neither is going to break your game. The deviations in rolling luck and player skill are going to matter more than a slightly powerful/weak race.
5E is a well-balanced game, for the most part, but its balance is reasonably robust. Little tweaking or minor creations aren't going to break anything.
