OK, thanks for feed back.
Geocities: I'll probally stay on it, since I found out that Japanese Geocities tends to put less adverts in (and I don't mind much). Also, some of my favourite artists have their sites on Geocities (>_> as if that has to do with anything... meh, just moral support).
Colours: I don't want to make the background really tacky with bright colours, images etc... less is more. But maybe not gray.
Layout: I need suggestions for this O_O can't think of other layout...
[edit1] *looks at Accident's link for layouts*: I dunno... the layouts look way too "pro" to me... I was aiming for a layout like in
this site,
this site and
this.
Content: I think profile, diary, gallary, oekaki BBS and links is enough ^^; But regarding images, more will be added in gallery sooner or later.
