Hey and welcome Chanhonam,
Under -> Themeforest -> Wordpress you will find all the themes. I recommend you look through them as they are more in detail and mostly have a ton more features than the link you posted from templatemonster.
And remember you can always buy a theme and modify it to look like that one you linked to, by modifying the files and images.
However, I do believe during your hunt on here you will find things 10 times better.
Good Luck on your Hunt

Hey ArrowSuits,
I like the concept you have, but here’s some suggestions that I believe would help and get the theme approved.
1) Darken the Font. 2) Create a border, or something around the drop down menu. It looks like it flows into the site. 3) On your menu add a shadow. This will make it look like its scrolling into the menu and not apart of it. Personally I would create the bottom of a circle type image for the header on this theme and fade the sides in so you still have the same style. 4) Add the Footer area. Even if its fixed like the top menu it does not have to be long or large. 5) Maybe even box styles or images around the different areas.
I think this would help, and wish you the best.

Hey @ll,
We have been on here for a few years now, watching the marketplace and building several projects we have yet to release.
Here’s my question, when we build a project we create the themes for cross platform (HTML, WordPress, Joomla, Magento, Flash Version …ect) . Should we start releasing them as singles or as bundles? ( Meaning all Platforms in one Download or Item ) WE have alot of files and we need to finally start uploading them. Maybe even, as singles and then a bundle?
Would that not make the price to high as bundles? What do you think?

if you still need help let us know

That would be easy to do with PHP , but can you explain more in detail what you are trying to accomplish and with what platform.
Many Thanks,
AfterLabs Studios
