Deadlift...stance is way too wide. It's forcing your arms out wider, bringing your torso lower, and you're losing good leverage. Bring those feet in a bit. Other than that your hips look good, so thumbs up. Good hip drive to lock out.
Squats...looks much better. You may even benefit from bringing your feet in a bit. Just monitor the angle of your knee compared to the angle of your foot to make sure they stay about the same. Play around with that stance and a slightly more narrow stance to see which feels better and allows for better depth.
One more thing...focus on keeping your elbows in about the same position throughout the squat. This will help keep your back tight, and help prevent you from folding over when you go for depth. When the elbows flare up in the hole, you will fold over a bit. You aren't doing that here, but just keep it in mind.
The image below looks very good. You are more upright, deep and look well balanced.
