Playing house:
Nice mellow vibes. The sub bass isn't really overpowering but it's there, it suits the song. The mix is good! You got the song pretty loud, without noticable distortion, good job!
Maybe you can add more excitement to the song by playing more with autopanning, adding something extra to the stereo width?
Against the World:
I hear a lot more stereospread than 'Playing House'. Pretty loud mastering again without distortion but the ducking on the voice in the chorus is a bit too obvious to my taste This gives me a nice uplifting feeling, I enjoyed the listen!
