It’s an ambitious painting for the first time outdoors and many good things in it! I’ve cropped it out of your image and guestimated on how it might look for adjustments.

I like the composition and your color- the reds and greens are always a great combination. I would suggest softening the trees edges and cast shadows, lowering the value of water reflections, and being consistent with the bridge pilings- and keep painting!

Looks very good to me. Evocative.
