[edit] I know it's long, but please read it...for some reason the people I tend to direct long posts at don't read it, hence I am telling you to read it, I hope it has the advice you need and helps you progress.
It's a good start, it seems you're showing you know how to work the mesh...but it needs more direction and structure I would say, of course that's something that comes with practice and learning and isn't something you can do quickly or 'just like that'.
In your Zbrush thread, I gave you two links, they should be helpful...In one of the links (the one that leads to the Seppuku Arts website) go into the Tutorials Section and look at basics...Now basics may appear patronising, but despite that and if you know how to use the tools, I'd look at it in detail anyway - as those are the tools I like to use - though none of the demonstrations are done in Silo, but they are transferable, hence when I picked up Silo I managed to get started straight away.
The second link I gave you, may appear like a lot to read/look at, but if you look at the progress, comments, sets of links in there, you will find ways to give your model more structure and give it a more accurate topology/edge flow.
One thing that's always important is to give EVERY polygon a purpose, not to have wasted polygons. The purpose may be small in some cases, but wasted polygons means a messy mesh and one that's difficult to make corrections on. However, the good thing is, Silo is a beautiful program, if you delete an edge, it will not delete the face until there's a gap, this means if you make 'uneccessary polygons' you can delete their edges right away. Also remember for a clean mesh, you need to avoid ngons (5 or more edged polygons) or tris (3 edges polygons) because they often stand in the way of editing and how the mesh looks overall - here you don't only need to delete edges, but you can draw new ones with the knife tool.
Of course never get ahead of yourself/skills, always start small, learn to walk before you run as they say. People are quite difficult to get right and takes a lot of work/practice.
Also, try to get your model anatomically correct, this means using reference images of people's bodies...The link to my 'making of' thread, will have plenty of reference image resources you can work from, even ones demonstrating polygon flow.
I'd give you demonstrations as to all that I am explaining, but I am at university, meaning I am living away from home and the computer I am using for 3D graphics and unfortunately this laptop isn't fit to run Silo 2 and doesn't even have a decent mouse.
But my advice to you here is, take what I've just said and the links I gave in your Zbrush thread and bookmark it all...because I'd probably advise not to model humans when you've just start learning Silo, I can see you're proud of this model and I see why you are, however, your current skills could be put to better use at less complex models and build towards a human model you truly will be proud of.
Good stuff, keep it up and good luck!
