My suggestion Penguin is to work on one modeller at a time. I started with the vertex modeller, went to spline and then went to metaball (which I still need to work on a lot!) Anyway, the biggest challenge I have found is the shaders, they are very complex, but when you get the hang of them, they are very powerful too. I think you will really like Carrera, my only real beef so far is the 3D boolean, it annoys me to no end the mess I get sometimes when I use that function. The render engine seems really good too.
