Tips?

I just recently started to get into the whole design and painting aspect in the game, I will spend hours making good looking designs only to get 2 or 3 downloads out of it, any tips for getting more downloads/uses?

If you enter them into the competitions on this site (see https://forums.forzamotorsport.net/turn10_topics3_Community-Events.aspx) then you’ll see good results if you get a win as it’ll be a featured design.
