So basically:
"I can't motivate myself and nobody helped me individually so I blame it on Striken even though I could've simply looked at other peoples art and try to improve by using those pieces as guidelines."

You did not ask for help anywhere in the submissions thread so I'm not even sure why you try to put the blame on other people.
The only thing that is holding you back from improving your art is your current mindset, change that and you'll have a lot better time plus more fun(assuming you actually enjoy art and want to improve ofcourse).
