Hello, Spud! We have three types of showcases: interior, exterior, and quest. Having one of these approved will allow you to work on the corresponding claim type.

For an interior showcase, follow the guidelines here: http://tamriel-rebuilt.org/content/guidelines-interior-showcases
Basically, use _de_ furniture, 2 stories/multiple rooms, nicely cluttered. We pay particular attention to whether objects are resting on their surfaces appropriately (bleeding or floating), and whether the items you put in follow a general theme and are appropriately leveled (for example, don't put a Daedric dai-katana in a commoner's house).

I don't know as much about the exteriors myself, but here are the guidelines for the showcase: http://tamriel-rebuilt.org/content/guidelines-exterior-showcases

For a quest showcase, you make a quest! http://tamriel-rebuilt.org/content/guidelines-quester-showcases
For quests, we are looking for cohency of the storyline, lore friendliness, good dialogue writing, and a working knowledge of how CS scripting works. (You don't need to be a wiz, just make sure the journal functions.) If you make a quest in TR's land, it may be suitble for inclusion in the final mod, but don't feel like this limits you to just TR stuff. If you don't have many ideas for a plotline, you can attempt creating one of the claims here: http://tamriel-rebuilt.org/claims/quests

For more information or tutorials, check out our handbook: http://tamriel-rebuilt.org/tr-handbook I hope to see something from you soon!

Cant wait to see what you create

Hi Spud, thanks for submitting a showcase. This is quite a nice interior, and it's great to see creative use of the in_hlaalu set like the upper floor, but there are a few things that need correcting before you can be promoted.

First things first, your lighting values are still at the default levels (which are much too high). Have a look at the settings used in other interiors in Balmora for some sensible levels. On a related point, there aren't any lights placed in the interior (other than the small lantern on the upper floor); again, looking at how lighting refs have been used in Balmora is a good place to start. Also, inhabited interiors like this need to have "Illegal To Sleep Here" toggled on in the Interior Cell settings.

I like the upper room design, but currently there's a lot of flickering from overlapping on the ceiling; I'd recommend reworking using a one each of the "in_hlaalu_hallt_center" and "in_hlaalu_hallt_centerd" pieces. 

On the main floor, there are at least three places where the ceiling isn't matching up correctly (see here). The in_hlaalu_hall and in_hlaalu_room sets can be difficult to combine because of problems like this, so keep it in mind when working on Hlaalu interiors.

Another issue (which is more of a subjective concern) is the scale on the kegstand and the banners outside the cell on the main floor. I'd recommend scaling the kegstand up a little (to around 0.7) and either scaling the banners in the cell to match the ones in the rest of the interior, or just swapping those two banners out for a different one and keeping the current scale.

On the positive side your file is clean, you've added a northmarker, and your ref placement is quite good (with a few minor errors listed below). I'm sure you'll have no problem fixing up the remaining problems with this showcase. 

A list of general placement errors follows:

If you need any help, or elaboration on the errors I've indicated, please don't hesitate to ask!
