Hi

You've got some skill I think your 365 drawing idea will take you skill to new heights.

The character in your sketch looks like she has her head turn a touch to the right but not quiet looking up out of sight.

to improve on your character drawing I'd recommend practising your character propotions, male and female.

I did this recently and it help drastically. I also did a few other practises that help in massive amounts such as drawing heads from all angels and tilted in different directions.

I hope this helps, What has helped me improve may not help someone else improve. The main thing with getting better at drawing is to just draw.

Keep it up
