I released most of the dragon bust 3d models from my Dragon design marathon www.deviantart.com/damir-g-mar…
You can get them over at gumroad: gumroad.com/damirgmartin
They come as individually purchasable 3d models or in two larger packs at 26 pieces each pack.
If purchased as a pack there's a significant discount.
These busts are intended for commercial use.
If you have ideas for a chess set, board game set, a videogame model or a base for illustrative work, with a bit of effort and creativity they can me modified and adapted to suit your vision.
You wanna create entire dragon, these can be used as a starting point too. They can be painted.
You can cut these models into pieces inside app such as zbrush or mudbox and pair different parts from different dragons to get something unique.
