I think the updated model is going into the right direction, keep on going.
On new projects I would say “never say never”. At the moment I have a long list of things I would like to try out. The last time I took a look on that list it contained like a dozen mod-ideas 
. Well, I have shortlisted 3 of them, but they all include not only re-design of existing assets but some severe coding and modding of the UI, etc. So before I even think about another project, I would like to get this stuff sorted out. Btw. one has the name “SheepBall” … what a coincidence 
.
