The bricks need to be aligned at the corners & the figure on our right should be flipped to match the light source. If you want to follow a tut, at least try to get the basics right.

Sorry but the walls and steps do not look right, a shame because i like the idea, maybe you could try to correct it

Well it's not entirely your fault, cause the author of the tutorial had some problems with the perspective. That entrace should follow the horizontal lines between the bricks, instead the entire opening in the original is ambiguous, in reality it would make no sense.
However you should be more carefull at step 6, the second part, where it said that the gaps should match., and the stairs should be from wall to wall.

If you have probs. with proportions, use the final result of the tut., and draw some guide lines over it. Use them to build your entry on top.

Thanks greymval Yeah i was having some difficulties with that, I think I will be drawing them instead. Will edit asap, thanks again !

Nice attempt at a difficult tutorial. I can see you put some effort into this and it is a learning process ... that is what tutorials are for, right? I think greymval's suggestion are valid and helpful.

Top work author...well done
