Hi Carl,
Aside from the debate around whether to post work at such an early stage for feedback or not, here's my thoughts on what you have so far.
There's no relevance to the name Up and Down Designs, I'm not entirely sure what connotations you would like the name to have, but is there some meaning behind it? Why did you choose that name? What's the USP of your company? Aside from the actual content being a bit up and down in terms of layout I think I'm missing "it".
Leaving the name to one side, there's a lot of different elements fighting against each other, you have the logo with the icon above, large "W e l c o m e" text, banners and work examples dotted around, an island in the top right? a piece of a book cover? Hopefully you get my point, it's all a bit confusing, if I was a potential client I'd be confused and probably leave based on that, that's before I've even seen your work.
My advice at this stage would be to pick up a pen and sketchpad and work out the layout, including all the content you'll need, and work out a design with a grid, with some flow, with hierarchy between elements, help to lead the visitor through the page, entice them to find out more, to see more.
I'd also think about your name, I know this thread isn't about the name, but I personally find getting the identity right first makes the web design process much more straightforward, for me personally neither the name or logo is hitting the mark.
Good luck and good to see you're valuing the feedback received
