Your first two shots are GREAT!!!
The shot of the trees is really really nice.
The last photo could be better.
I’m really proud that you are sticking with the course and improving your photography.
The main idea is that you understand the assignment!!! Good work!
* on your photos beware of “camera shake” Are you using a tripod?
I highly recommend you use a tripod for these types of photos.
Your photos will be much sharper.
Onto the next one!
