Darktiste Sketchbook

[Hobitt]

Well right now for the last few pages i don't see any personal work at all,all i see are very low effort studies,and at this point i have to ask, do you even enjoy doing these? because clearly if you did you would put more effort into them ,youve been sitting in a comfort zone for a very long time doing stuff that is completely useless to your development as a artist, and if your goal is to get a job doing art then you are a long way off because no one cares for this stuff people want to see illustrations and ideas ( as many people told you a hundred times before), you should do personal pieces where you put 100% of the effort into them since thats the goal, studies are secondary to that.Look at Fedodikas latest painting with help from other users he pushed himself a lot and got great results, that should be the goal to do things you feel you are not good at.And you know this yourself as you sed "My method is to generally do a few study to gain confidence that i understand the principle and then inject those principle into my own work" but the thing is you aren't doing this there are no personal pieces in your sketchbook, focus less on "methods" and more on doing things you actually want to do, art is not rocket science the more you do of something the better you will get at it.
So it is up to you, you can keep making lame excuses like you did for a long time now or you can take the matter into your own hands and start actually improving and start reaching for your dreams and goals,by doing what you actually enjoy.
