Ive given you some of my initial feed back on this sir indigo ^_^. Dont let the naysayers tell you that it has to be done in flash, we'll get you something up and working in javascript no problem. Also, if you want to avoid the whole frame/resize issue, i would suggest you plan to have your content contained with an inline frame, so you can scroll anything necessary while preserving the border (you can even have those drop-shadows the tiles push onto the content area overlap the content with translucency if you set it up correctly.
about the art itself, not only am i looking forward to a new sprite design, but also some more organic elements within the pgae itself, more plantlife perhaps, the boxes/crates seem out of place. also the boxes as they are colored now seem a bit too plasticky and not so much wood... perhaps on the sides you could shift hues to either a cyan or a magenta... and take the 'shine' highlights off the box, perhaps add some granular pixels to give it some texture.
One last thing looking at it, while i like the arcade-like effect of the title of the page itself, i am not getting the feeling that it really matches the rest of the stylized content on your site. i think something more subtle (yet equally as colorful) is achievable to make it look a bit more artful and flow with the composition of your site a bit better? perhaps its not necessary though.
Edit* Ahhh sorry Tiny g. i think 'naysay' has a negative connotation i didnt intend to imply. i do agree with you that the best approach to the whole 'portfolio' idea is to keep it as simple as possible. though if you decide youd like to add a feature to your site you feel makes it stand out, i think its certainly worth a shot, even if its novel or trivial in its functionality
