great job, good that you analyze yourself, but you need to go darker/lighter in all your pics.. need to push the value of the tones harder...take a mirror, sit infront of the window (during the day) and rotate your head, try to see the dark parts versus the light parts..
and i tried a overpaint on one of your sketches, i did it really fast so i hope you understand what im trying to say with it... think of the face like planes (as i told you in stockholm, but i guess a pic explains it better)
i kept your anatomi structure as a base, cus maybe you understand it better if i do
there ya go you really thinking about it now !
i thin you have a good start and allreddy show some progression some one suggested drawing on the right side of the brain up there ..i suggest it too every one i know tha thas gone though the exersizes has really really improved verry quickly !that and it will give you a pretty brodrange of terms and ideas keep going mate ! do it every day with out stoping
oh you can try some of the feng exersizes to get your muscles to listen to you when you want to make a streight line and elipse/circle .. jsut make soem dots on a page and go form one to the next in a solid stright line then try the same thing makeing circles and curves .... sinc eyou jsut started your body is probly not used to movieng and controling your limbs in this way so you will build up a physical memory that way .then i suggest movien on toe th esuggesteion form the fella above .. do basic shapes circle triangle square ... then go to cube sphere piramid cilinder .... then head on to waht davi suggested and render them with full values .. also look up the words and such and get as comfortable with the terms as you possably can <this will help alot when people make suggestions and your try to learn form tuts >the betty edwards book will really get you firmiliar with all the tearms and various tecniques .another book thats great for beginers for quick refrence and a verry simple intro to construction is how to draw the marvel way .. its not the best but i think since it has verry limited and simple format its verry user frendly <not over whenlming at all and a bit fun too >eventualy <and it wont take too long > you will start seeing things as their basic shapes and you will be able to make out diffrent surfaces of those shapes and it will be verry easy to apply light <and lack of light > to them
keep going main thing is do it eveyr dya no matter waht evne if you little boged down with school and such kik out a couple shapes and such and above all have fun with it
<i thin you have a good start and are doing well mate keep going >
