Hi zymon, that's a very complex organic object that is not easy to define in some concise way like by a few 2D profile curves. So it's likely to be a pretty advanced and difficult model to build in any program. It's a bit hard to say what would be the best program to use for it, but maybe ZBrush or 3D Coat would be the most suitable.

It could be possible to do it in MoI probably by placing many cross sections and using Construct > Loft. But you'll be placing an awful lot of cross sections and needing to manipulate them in 3D space so it's going to be quite difficult.
