The curvature of the feet is wrong and the chest display needs work, but the bit I’m stuck on is the metal grid for the face.
I don’t know how best to model an object like that. What I’ve been messing about with is to take a uv sphere, delete all but a quarter of it, stretch it and then selectively delete faces.
Doesn’t seem like that’s the best approach though.
A good way to do this is to select all the rows above the bottom one and input a value when scaling (for me 0.98 worked), then you can deselect a row closest to the bottom and press Shift+R to repeat the last action. No right or wrong way to do it though, so long as you end up with the right shape.
For me [Target Normal Project] mode worked best but feel free to try other modes too, you can also at this point “move” the object back and forth (it will stay aligned to the “egg”) to get the best fit.
