Thanks ARMORMAN for your reply, it means a lot when senior artist like you praise rookie work.
I haven't search for instructions, as I started to assemble Marine as soon as I found it in your post.
I checked out Silveroxide
post with instructions, and found it very helpful, but what could be problem is that I think his model isn't 30mm, but bigger. On pieces he using pen for curving paper, I should use tooth stick

.
Anyway, I'll try to assemble Marine on cardstock 150g/m paper I printed in color, and see what's going to be...
btw, those pieces of yours are real art, especially jet bike and scout marine, and that red Chaos marine is genuine, as he is deformed by Warp
