Hey, saw your post in the lounge! I'm interested to see how this is going to go when both eyes are alreet, but as far as I can see you've been doing a pretty good job already and your attitude is great. diggin' that pencil work!
going on what Sundance said, I'm thinking maybe we've got a common bad habit (mine's in that I take my sweet time laying down the sketch for my studies, but as soon as I'm drawing stuff from my imagination I just want to get straight in there and draw the whole lot, which results in plentyyyy of anatomical problems. and disillusionment and so on and so forth. but hey! here's to breaking bad habits)
but your sketchbook is looking great so far. keep going for it, keep drawing (I don't think you have any intention of stopping!) and good luck to you
What an overwhelming lesson to all artists! Be not afraid of absurdity; do not shrink from the fantastic. Within a dilemma, choose the most unheard-of, the most dangerous, solution. Be brave, be brave! - Isak Dinesen
