my theme... definitely varies from av to av. I don't really have much consistency when comparing past designs I've done. Within each av I usually have some kind of colour scheme though, and go either light or dark... or sometimes a mix? <_> LOL I don't really know.
I think I make avs moreso based on 'oh this looks good together' rather than a specific theme. With this one, I just wanted to do something cutesy, then the items just kind of came together.
I....have been a cyborg for almost 7 years. Which blows my mind in the strangest of ways. It makes dressing myself up a loooot easier, since I don't feel tempted by a lot of items. Once and awhile I'll get envious of people with faces. But it's rather fleeting.
I'm known for my more "lolita" style, I suppose: sweets, frills, pastels, toys, kitties, etc. I love the style; it's my favorite. But what most people don't know is that I really have tried to slightly modify my style by integrating darker colors to my palette (in my inventory). I'm already very happy & confident with my current style, but I thought it would be fun to try out new styles for the heck of it. After a lot of experimentation, I still haven't had any luck! If it's meant to happen it will someday-- that's what I figure, at least. ^^ For now, I'm happy in my own pixel skin.
I generally don't aim for any sort of theme, but one day I thought it'd be cool to make a completely grayscale avi, which I managed fairly well. Then I found this spectral possession item and didn't hesitate to turn it ghostly. biggrin
