Really impressive stuff - to this day I still have to even approach Blender in any way other than casually trying to put shapes together in an attempt to make something resembling a blocky low-poly model [and even those were still just messing around with the editor, since I didn't have a proper planning to model out a character yet], so it's SUPER cool to see that you've rigged a whole model to strike poses like these in your renders.
Thank you. This took a very long time to put together. From modeling to rigging, and this is coming from a person who mainly animates. So I appreciate you taking the time to reading my post and commenting. ☺️ I suggest you practice. It's very fulfilling and satisfying when you create and see the final results. It's almost like building a puzzle image together.
