But I have some issues with the lack of detail.
You could add a stroke and a drop shadow for a 3D effect.
Other than that, it’s really nice.
Also, I wouldn’t recommend black; as it doesn’t fit with thumbnails such as GFX.
Maybe a small grey colour with a brighter stroke would do the trick.
But, you don’t have to take my opinion as I have my own style, so do you.
I like my style better than anyone others, as I’m used to it.
You could just ignore me though, but I’m giving you some tips.
The first one looks off-center, it may be a good idea to move it more to the left. This is a bit nit-picky, but the watermark in the bottom left stands out too much. I think you should maybe have a picture of the game blurred out as your background rather than solid colors.
The text logo looks great though, however you may want to look at having design guidelines since you seem to have two different fonts for HOUSE and they are at different angles. I prefer the second, but that’s just me!
