I edited my post above referencing your request for advice with perspective. Hope it's useful!
I see what you mean, but to be honest, I've never truly liked the Minish Cap Goron Sprite, and I'll tell you why:
The palette used. I never understood why they were brown when Biggoron and every other goron in previous games were yellow-ish, heck even in BotW they are yellow. In Wind Waker, which style is practically Minish Cap in 3D, the gorons were still yellow.
The front, side and back view all are completely independent, they don´t line up in height. For the side view the arms are longer, the legs and feet are thinner than the front view, as the feet on the front view look extremely large, and on the back view the goron is just shorter than the other two sides. I put a size comparison on the attachment so you see what I mean.
Then the eyes are on the front view shaded while on the side view its one plain color.
I know what you mean when you say the feet should be hidden, but i've never personally liked that, you hardly see anything, which I guess its why they made the feet so large in MC.
The feet I used for the Goron are actually the side view of the MC goron, just tweaked a bit. I edited the sprite based on your edit, and I made different versions of the feet to see which one looks best (I still like the first one
)
I also made the Goron cross his arms using the Goron Chief sprite from King Mobs's Shadowgazer.
