Tthanks for the support guys, it means a lot!
Update time!
Today I managed to buy 3 forgeworld warhound titans from a local player for a very discounted price. It looks like they weren't primed, so the paint has already chipped off on some parts, but I can't complain because they were very-very cheap.
Also, I tried to fill the tiny gaps between the 3d printed layers by rubbing a very small amount of Procreate on the model. It looked quite effective, but I will only see the end results when I molded and casted the tank. Unfortunately, I'm out of superglue, so I can't start molding or assembling. The next semester starts on monday, so I will buy a pack of superglue near the campus and then I can mold the not-chimera and the not-falcon-waveserpent tank. I need the superglue, because I designed the tanks, so they can be molded in a single side mold.
Until then, I'm off to sculpt details on the Baneblade. I want to finish it in two weeks, because I want to move on to other projects. (1:72 RCW, Epic turret variants for the Hydra etc. etc.)
