how are my drawings not strong enough?
I am having problems with my schooling, I have study for so far 3 years at my community college in General Fine Arts and I have improve from where I was before, but the issue is my professor is telling me that i am decent but my drawing skills aren't strong enough. I feel like instead of explain why I am not strong or what elements I need to push it. She is suggesting that pull a warhol and the factory or do colleges and tell me a bunch other stuff. To be fair I should of ask her to explain during critique,
So, What are the reasons for my drawings not being strong as they are? and here are some drawing that have done.Attachment 1702615Attachment 1702615Attachment 1702616Attachment 1702617
