I got over my hate of drawing cars and other vehicles when I bought a car and accidentally became a car girl, lol (I was already a boat girl, always have been since childhood). Now I'm one of those people who recognizes cars on the road and can name the makes by their year and design. So, while my brain doesn't handle inorganic shapes very well and I'm still kinda poo at designing new cars/vehicles (if I have to make them realistic and not just bubble vehicles for my comic), I don't hate drawing them.
I hate having to design and draw ornate/elaborate clothing like, for royalty or something. I can almost never get the designs right that seems opulent/rich and not like, a bunch of ugly messy lines and squiggles.
I also hate interior design... even though I've been trying to get better at it for years, I just can't wrap my mind around elegant solutions to problems. I think too inside the box and everything winds up really devoid of character. D:
And I struggle with drawing modern or futuristic cities because it's both order and chaos at the same time and I DON'T know how to balance the two to get the look I'm going for.
