40/60 share is good. I’ve worked with few good and bad developers. Good one takes up a lot time to make the theme, bad ones makes it even worse. In order to value developers work I offer 100% share for 2 weeks once the item is up for sale. Providing bad support will result the item to loose sales and bad feedback. Also I prefer not to sell the PSD design with the coded item, it helps the designer to get some sales separately. At the end respect each others work and keep up the good work.
This is what you get when you ask a friend to grow some Photoshop mustache XD Thanks to my friend s@p for doing this.
Client bought one of my PSD theme.
