I agree with @swikni – Good sculpt overall, just in need of a little TLC. There’s a big lump under his left arm-pit area, the eyes could use more definition (small detail size [more polygons] and subdivide edges method for details/creasing).
Overall though, the shape of the character is good aside from the backside being too flat. Plump it out to secure a the general roundness.
I’ve recorded your primitive submission and this guy, which means an A for effort/quality but a B for completeness.
