very nice, Ashingda 27. amazing work
some suggestions (for anyone working on this), and please don't take this as direction at all since jimpo's vision is what matters; i'm just throwing this out there:
depth - stagger everything, depth-wise. right now, everything is basically on 3 planes; front, middle, back (plus landscape).
edit: yes, i see this suggestion is somewhat- contrary to the box-art examples above which
do have the basic "3 planes/distance levels" that Ashingda 27 included, as well. just going with the vibe i'm getting here and now
a) personally, i'd like to see the fighter up a bit (and scaled down some to effect distance). maybe even make the fighter "toe-to-toe" with the cerberus creature or the orcish enemy.
b) the harpy is in a "lingering, watching from a distance, waiting for an opportunity" pose so i'd push her back some.
c) i love the oversized, flowing cloak on the malice king (if i'm remembering his title correctly) and he's the center of attention here, as he should be. but, i would make it more subtle by pushing him back quite a bit, into the mountain range and have his cloak flow/fade
into those mountains (it almost does already). below him, i would present an ominous cave/catacomb entrance which would reflect yet another aspect of what the game is serving up. these elements would, i feel, give the impression that all these terrible creatures, the mystery and treachery of what waits inside the dungeon, and the challenges of the landscape itself, all stem from/are caused by the malice king.
d) the dragon might do better in a turning-in-flight pose "coming in" (vs profile) from the top-left corner (more background than fore-) and the wraith-critter might be making his way out from the dungeon entrance? pushing them (and the king) "away" would also free up the center sky-space where the game's title text could be placed.
props - as per the demo and screenshots, Dego contains many varied tiles and tilesets offering up lots of detail to keep things interesting. flaming braziers, bridges, stone pathways and pillars, monuments, stacks of firewood and campfires, trees, stumps and bushes, skeletons & tombstones, fences, scarecrows

and all the underground amenities, to name (quite) a few. i think it would be nice to show a few of these things in the scene.
again, this is all
my opinion, offered for consideration and nothing more

what
ashingda 27 and
ultimate_h are posting here, frankly, make my mouth water. and, i think both deserve proper feedback and praise. nice work!
