About the gdshaders stuff - I just figured its worth mentioning since its not stated on the page here; not everyone comes from reddit so worth mentioning in a broader review :p
It certainly is a good learning tool and a start point for further tailoring, and the current price us fair given the updates and attention to the pack, especially given that older purchases get the updates for free; no complaints there. Looking forward to your future work, not just with these effects but in general too.
