I'm no expert on websites but I've made a few.
Here are some observation /opinions that might help.
in top left corner of your site on first page is unnecessary as you are already on the page the link links to.
If you can move the BBC News link down to the bottom of the page that would be a better position than the top otherwise you are encouraging people leave the site almost as soon as they get there.
It would be helpful if you explained the who, what, where, why, how, when, and other about you and your designs.
For example: Who are you? What you are doing with this site?
Why do you create these designs? Where you are located? How do you create your work? and other newsworthy explanations so we have a better understanding. Also, this would help search engines find you better because you will have more keywords and descriptions that people are looking for.
Can you change the Link/lightbox_public.php link to the name of where it actually goes?: canstockphoto.com/lightbox_public.php?id=nqjqqlo and or a link to your portfolio on canstockphoto, canstockphoto.com/santosalaksana/
You have (Please comment) on the bottom of the page but I see no way to actually add a comment.
On your page link Peta Situs
the first 2 links Lipat semua
whiteflower88.com/sant?=whiteflower88 don't work.
On your 3rd page Kegiatan terbaru situs
all your 23 links that say DESIGN GRAPHICS White Flower disunting DESIGN GRAPHICS
just lead back to the 1st page. You only need one link back to 1st page if any because it is listed in the left side of page navigation.
The lebih lama page on bottom of page is filled with more links but most of them have text but no pictures which is what I think you intended.
Hope this helps.
