Starting to come together nicely. Not sure if you've thought of this, but a 'rubber' sealing strip along the bottom edge of the screen frame stops water coming through underneath it and gives a more finished look.
My trimmer gave me a suitable length of open 'P' shaped seal and I can't seem to find it online now, but there are lots of options. Check out E Type edge seal ATJ1927 in the link as it looks suitable -

Keep up the good work!
