hey you have a good sense off presentation and rendering but I dont think dab is about rendering here. this lesson mainly focuses on breaking down subjects into basic forms and building on those basic forms to achieve a recognizable solid thing that is similar to the referance image. to do that you must use solid unbroken lines that have been plannned out before carefully. but here you use very broken lines that seem to convey the larger form very well suprisingly. but that is no excuse not to use basic form as your building blocks. you seem to not have your any of your homework critiqiued. which is very bad actucally because your lesson 1 has all of these foundational mistakes that could have fixed so I'm recommend getting everything critiqued before you move on to whatever next lesson you want. and there is gonna be a lot of homework and I mean a lot of homework. first focus on using your shoulder to commit long unbroken lines. before comitting please make sure to consider where, how loong or how curved you want to make your line come out. and sure to think of large forms and not smaller ones and forget about the texture detail for now.
