My first fly setup, any tips/comments are welcome

4wt orvis hls I think 8 foot that I inherited.

5/6 white river reel with 6wt line (not sure if it will work well with a 4wt rod but the guy at Cabela’s said it would be okay for me)

And some other goods

Please give me any tips, suggestions, critique anything, I’m all ears because I don’t know anything about this and I’m trying to figure it out
