Hello Sirina,
Ofcourse that's fair! It's more than enough.
Here is a screenshot of the upcoming heavy snow storm effect. ;)
If I can find some extra time, I would like to explain it to you. The values part is the easiest and if you know which car you want, you can also tell me and I'll do the research and fill in all the values myself. The sprite part is of course the hardest. I suggest you use a program like paint, but more suited for pixel art for games and animation. It's easier when you can work with multiple layers. I'm also trying to draw one myself. It's a tedious job. I've pretty much finished the sprite of the car facing forward and I'm using that sprite to draw the car at an angle. I'm also using picures of the real car below my drawing so I can trace it. There is a website of a oldtimer dealership here in Belgium where they make 360° pictures of every car they have. That's where I get my pictures from, from that particular car that I'm drawing. I'll try to make some screenshots in the future so I can explain it even further.
