Hi Mark, and welcome!

I really like this collection. Just some minor comments:
1. I love everything about this image except is seems to be tilting slightly downhill on the left side. As I look at the horizon, it seems it should be leveled off a bit. Of course, that could just be my eyes .

2. Very nice macro shot. I'd like to see a little more depth of field.

3. Love the lilly.

4. Nice composition. I'd like to see a little more shadow detail.

6. Winter Scene: beautiful. Lovely light.

These are very nice overall. Thanks for sharing.

Jim
