I have moved my kits over to the Artstation store, check it out! My spaceship kit has been purchased over 150 times so far on Gumroad which is super cool, glad to know people are liking and using the kit. Also check out the marketplace for other cool stuff people are selling.
Full break downs of the kits are here
