I didn't know about that DAE. I'll spit out their website asap.
Was finding it very irritating that I have so much trouble with anatomy so I figured that
I should start studying anatomy more in depth.
Try not to rush (wanting to learn too much too fast) because you'll only end up frustrated in the end. This path just needs to be taken step by step
One thing I miss here are studies from life (I mean from real life, not from photo).
Those are a must. I think you should make that your number 1 priority:
draw from life every day. Don't go to bed until you have!
And do this forever.
Trust me on that one.
If you can, get some life drawing sessions at your school.
If nobody mentioned this there yet, approach your teachers and ask them if it's possible, where and when etc.
