the second one seems clumsy, with odd, arrows on the head and a kinda shitty head overall, poor eye placement etc. also the legs have tons more detailing then anything else and all the details seem unnessecary, it seems over complex for almost 0 reason (I do this with my heads a lot actually, im trying to stop too) you need to have basic shapes that define it and either just shade/support them with other stuff, but dont just make 10000 parts
