They look great. Good decision, can't see any clears there just a milky paradise with a few ambers too I reckon. High quality buds!
Don't worry about yields at all, just focus on keeping your plants healthy and trying to hit the ideal environment, that will give you the best quality and yields will be what they be.
That's a great first grow and as you progress you'll probably want to push light and nutes and whatnot in an attempt to get higher yields which is fine but quality is always number one for us home growers. Looking forward to your next grow.
