This is the first time I did sculpting with blender. It is not my best work, but you have to start somewhere.
I think I can get rid of the noise If I renderit with more samples.
of course you must start somewhere, sculpting isn't an easy thing, yet I choose to love doing it and I bet you can get better with practice, trust me just do this for at least 5 days or 4 and you will see instant results. Remember you learn from your mistakes! Just one thing, it's a bit too noisy but it's okay, I understand that Blender is a heavy software and not every computer can carry it. (Wait until you try to animate :( )
