This page would be the standard page, as in the first one you see when you access the portfolio.
On the left we have some sort of mini-gallery that contains a limited amount of artwork, selected by the artist himself. Look at it as 6 featured deviations ( which could be selected through some sort of slot system, similar to the customize frontpage option )
Below the showcase there's a little box with your most recent devations ( with small thumbs, to make your featured deviations stand out a bit more ) and a link to your gallery.
On the right we have the fullview for the selected deviation. ( standard this could be the first, or a random, from the 6 featured deviations ) With the title, description, a link to the deviations and the number of comments and favourites. ( because one wants to brag with the amount of favourites I have )
This page contains everything one needs to know about you once you captured his/her interest: Profile, Bio, Resume, Awards and reviews.
Now this a a feature I really like: it allows others to write a review about you, similar to devious comments BUT becouse this review appears on your portfolio ( a rather special place ) you would have the option to approve the review first, so you would have total control about what appears on YOUR page. ( what do you think about my review by the way )
The most important page of your portfolio: even if your portfolio is sexy as hell without a contact page it's completely useless
On the left we have the standard contact information.
But on the right people would have the ability to send a note directly to you. Even people ( talent - scouts f.ex ) who aren't logged in to deviantART. ( the note could be send by some sort of bot account.. )
Since the easier it is for one to contact you, the faster they will do so.
