Advice for logo design and Liveries?

I am new to making liveries and want to improve my ability to make them. I would like to hear some advice from other players on how to make liveries, and particularly advice on logo design.

Thanks! 

Just my 2 cents but try to make your liveries more bold and unique, and don't make them too messy or crowded. Use a good stylish yet readable font as well. For logos, I can't offer much as that's an area I'm still working on too.
