New to this and would greatly appreciate some help.

Sorry I realize this probably isn't the best place to post this but I couldn't find anywhere else to put this thread. I am completely new to drawing but I saw this program on steam and it greatly interested me. I recent saw some pictures similar to these on deviantart.com and that has kinda inspired me to do this. I have no idea where to start, could anyone maybe help me? I was looking into getting a small intuos pen and touch to start off with. Thanks in advance for the help.
