Gid 617,Desert journey
That's good as far as it goes, but there's not much to engage with there. Something to heighten the urgency would be nice - a vulture picking at those bones would be a great addition. I did like the tan/dark tan variation, but I think it would have been more interesting if there were more elevation changes (e.g. see Rocko's Dune
MOC). Also, there is no difference between your three photos. At least turn things around so we see this guy from different angles (bird's eye view might be cool as it could be a vulture overhead). One last issue was that there was nothing that said 'castle' to me. That scene could be from a thousand years ago or last week. Perhaps using a different fig would help here.
Matthew,Fire and Water
This is fine as far as it goes, but could have been so much more. I understand that the photos make it hard to see some details, like the fronts of the houses, but perhaps camera angles would have fixed that. The houses themselves are simple rectangular floorplan - these could have been changed a bit perhaps. My main problem with this MOC is what it was missing. This is, presumably, Laketown (from the name, and the fact that it was also your MELO entry). Laketown was built up on piers, which would make this much more interesting. See, for instance, some of Blake's entries
last year). Even if this isn't supposed to be Laketown, and I'm not going to hold you to that, since you didn't even say so in your entry description, the water outside the walls is on the same level as the street, which means this town is going to be in a lot of danger of drowning, even if there's not a dragon about. And that, of course, brings me to the other glaring omission. Assuming this is Laketown, and we're in the chapter of the Hobbit 'Fire and Water' (your entry title), there should be a dragon somewhere about, and the soldiers should be rushing to fight him off. That inclusion would have elevated this MOC from pretty good to epic. Even if we go with saying this isn't from the Hobbit at all and the allusions are accidental, well, then, you've got an unexplained fire on the one side, and even if it isn't due to some dragon intervention, you'd expect the other figs to be rushing to put out the fire.
DeetCr,Reach the stars
This suffers from the problem I mentioned in an earlier critique of 'too much busy-ness'. You've got a jumble of gray and dark gray in the building, on the ground, in that rock wall on the side, and even in the smoke. It would have been much nicer, IMO, if the ground had been all dark gray and the tower all light gray, or vice versa. I do really like the details around the door of the tower, and also the detail with the wedge plates around the windows on the upper floor. That little tree is very nice, though it seems a bit of an afterthought. On the building's interior, it always looks wrong when people show a cutaway and there's only a plate or two for the floor between levels. There should be some sort of pillars or rafters to hold one level above the other. This could be fixed pretty easily with some brown half-arches, or inverted slopes, as supports for the upper levels. The telescope is cool, but the hinge point looks way too fragile for that huge telescope. Oh, the chimney should extend much higher. As it is, anybody up on that top level to use the telescope would get a face full of smoke every time the wind shifted.
