Quality poster - captures the feel of Star Wars and wouldn’t look out of place alongside the classic OT posters of the early days (before the SE).
Fair play to you for coming up with your own content too - you’re right - there are very decent pictures out there for a complete Original Trilogy with that pre-SE look.
I can only imagine the hours you’ve spent experimenting, tinkering, and then perfecting it - really well done mate 😃
