Hay man from the sites I looked at I think your portfolio is pretty good TBH, I would disagree that you have coded them to the latest standards as you claim, that and I could get them to render in twice the time, but nice portfolio still the same, shame about the coding TBH, that an a heavy use of images are really the only things that lets you down from what I've seen.
However on to your request it is actually a pointless request that wont better any one, maybe you, as the links will go in a directory called links and this will not be index or any links coming from it will be devalued as a result. Now if someone links to you off here and they put your link on a none penalized page then you will get equity, they will not.
That but as both links will be a reciprocal link, if they are counted they will both be devalued for that reason.

Welcome to DF by the way.

PS: There is also a signature function that would save you time constantly adding a link to your site and your name, go to My DF and edit it in there.
