In those pictures you can see guitar for Star Michael and Star Luna.

First of all, because of animatronics and don't have better expierence to make REALISTIC human animatronics, my, urgh, OUR game will be in pixel/voxel style in 2d and 3d (2d for rpg gameplay parts, and 3d for cutscenes and main gameplay)

Also I'm going to finish bass guitar what I forgot about and I finished drums what I'll show you in next post, and acoutsic guitar (Idk if its good in Rock group) that I'll finish soon. :/

all models in game made by me (using blender 4.2 and Blockbench)

Thanks to @sonicEblan who helped me with design of musical instruments
