Yeah the cheese wave was sculpted in zbrush then touched up/remodelled afterwards. However the splash in the first illustration was done a little differently - we did a bunch of fluid sims to get reference for how a splash should look then, we modelled it from scratch using the fluid sims as a template, but exaggerating it to look smoother, stringier and cheesier.
I’m new to 3D modelation, and i wanted to start with cartoons. Believe me that after seeing this work with blender i’m even more motivated to learn and start creating my own chars.
Thanks!
P.S: It’s amazing (in the wireframe view) that such a great character is made with few polygons (compared with other works that use much more and achieve maybe less expression/cartoonish style)
