Your previous post was from October 2016. You should've reached more than 100 anatomy studies by now. Probably 1000 already in 3 years. What happened, lol?
Are you using a base mesh. I think you would learn more from starting from a sphere or other primitive. else you will most of the time end up with a similar shape like you have now. I don't see that many differences between the sculpts. I'm doing a challenge like this myself. I'm sculpting some piece of anatomy myself…
@Grey_Rift Thank for the feedback =D ..ya, i always start with sphere for every sculpt. In the beginning, it really hard, but let us keep the hard work =D !
