hey, dont give up. you can do it! i started from completely nothing too, no background in doing 3d and stuff. sure, i didnt get what i expected at first but i keep trying my best to improve. its the journey that counts, not the result. keep going at it! 
I wish I could do it, but I want it to look realistic and it doesn't. Dx I've tried working with tutorials and everything, but no luck. It's alright, it's not a life skill.
