It looks good, but the background is dark, which makes it hard to see the lines coming off the logo. Is the floor broken tiles? If it is, you might want to show a few more tiles in tact to make it more obvious what the floor is made of.
Looks cool though. Liking the texture on the rock and the general atmosphere! =)
Ah, also, this forum has a zoom/unzoom feature, so you can just post everything in 1x to save yourself a bit of work. Just click on an image to zoom in, control + click to zoom out. =)
