Pictures are superb, site needs a bit of work, My comments;
I have 24" widescreen, and everything is set to the left, I would imagine on most displays it would be the same, apart from the one you set it up on.
I dont have a problem with using tables, just make them invisible/blend in, and know their limitations, for menus there are loads of free sites out there that will create a menu for you, in just about any format, colour, style you like, do a search. Freesite is a good place to start.
There is no home button, no way to return to your home page, apart from from using the back button, not elegant, having the menu set either to the left or the top as a constant on every page may be a better way to do it, see above.
About the artist, is good, from a description point of view, however you havent set any limits on its width, it stretches across my whole screen, set some boundarys, use the table setting to sit it in the centre.
Also think about links to the awards, if they display your work all to the better, if they dont, create one to the work that won the award.
The pages of your works, bushcraft and misc have the same problem as the home page, its left rather than centre oriented.
Also the Bushcraft page you have set a white background over which the wood effect background displays your work, however on the misc page its all the wood effect, personally I dont like that, one or the other.
I'm curious why you have your header with a distinct celtic dog format (Lindisfarne at a guess) over the top of a Korean background ? A very faded version of the blue/green mosaic, would I think work very well across all your pages, again personal preference.
To be frank, from what I've seen of your work to date, in no time at all you'll be able to afford a professional company to design a website for you.
Also I've been thinking of asking you to do a commission for me, I think looking at your work has crystallised that for me, I hope to be sending you PM shortly about that.
Regards
Stephen
