My First Engagement

They look a bit soft to me, could be the style you were after, or maybe its the small images. Composition is good

I really like 1. The exposure and wb are nice. Unfortunately, the cropping really hurts it. You cut off both of their feet, and I would have liked to see it a little wider.

2. Bad lighting. Really bad lighting, over exposed and you shot a little too tight again, cropping off the top of his head, and 90% of his hand.

3. Cute moment, good composition. I like it.

4. A bit over exposed, and cropped too tight.

^Pretty much agreed on everything.
The first two just has a cramped feel to them.

I think #3 is the best of the bunch.
