One: Nice shoutout to Moorcock and derived bands:
I appreciates that.
Second: Super nice job on the models. With the box label thing on the picture they look like they could be an official GW pic from the period.
I also agree with Cypher226, those plastics are the worst GW still has in production. Even some kits that look worse, like the Space Wolf on the flying sleigh and the current Daemon prince, have an edge on them by at least being in scale with the rest of the range.
These guys had arms that were bigger than Space Marines when they first came out. I remember being so hungry for IG plastics when they were first released and just looked at them and thought, "nope, completely useless when my IG are bigger than my marines in Power armour."
The Catachan old models were even problematic going with the fluff, although they were much better models.
The fact that they had a 5+ save seemed a little out of tune with what was being represented in the figure. I thought they should have had a separate entry where they had a better cover save but no armour save.
Anyway you've done a bang up job with those figures and I'd happily play against them anytime despite my hang ups with the actual models.
Here is an animation of the original Catachans in action:
