i hope its not too late to reply to this. my work isnt half as good as this, but dont worry. just experiment with whatever medium you like or wanna try out and dont pressurize yourself to make make each artwork perfect. that will come naturally in time. confidence is key. so take your time and do some practice exercises before you draw each day. you could also try doing small thumbnails before you do a final piece so that you can work out any errors beforehand ie.composition and pose and stuff
