heya, looking pretty nice, although it could use a little more 'spice' I think. Wordpress is a great blogging tool but I'm not sure about the use of it as a portfolio-site but I think it's really useful to show people what projects your involved in and what you're up to at the moment. Btw, dA also has a portfolio component that can be set-up easy and you can put stuff from your dA gallery in it as well (http://portfolio.deviantart.com). Some remarks / thoughts on your site and wordpress:
- the banner image is a bit flat, maybe use some more color or maybe a more lively composition of some of the cool things you made or maybe tilt can create a cool logo for you ;D (if I'm correct he's in that business...)
- if hosted by wordpress itself, you are limited in plug-in and layout capabilities, but you can still choose from a large set of predefined templates. Check the 'appearance feature' in the admin tool to see a gallery you can select one from. There are some that have a little more spice
- if hosted by a 3rd party you can upload many templates (thousands can be found on the web, free and paid ones) and plugins. Many parties that host sites now have wordpress capabilities for no extra fees. I started one at Wordpress to see how it works but now plan to move to one hosted by my webhoster.
- as for pages/content: try avoiding 'empty pages' such as the 'cartography landing page' which only states to click on on of the submenus (tbh I'm guilty of doing that too, chosing categories and menu's always takes some thought. Maybe just create a page 'cartography'(without the submenu that took so much time to make and put the categories as links on that page, maybe with your best one from each category featured...)
- as for menu items, maybe add a link 'commission' or something so people know where to click if they want you for their job
anyway, I think for a first time website it looks pretty slick already... good luck in the wonderful world of website building (still working on my custom build portfolio site ... ) cheers!
