u can add in some trim here and there like ive done in brown here. maybe wood trim, smaller bricks, darker bricks, anything to add some contrast and make the depth stand out lightning flashes n sounds would b cool. also small details like stagnant ponds with bugs flying above them, bugs around lighting fixtures, vine decals up the castle, and if repetative textures are being a problem, open the textures up in photoshop and give em some grunge, u can mess with the offset and clone stamp tool to make it nice and seamless still, but have like 3 or 4 different brick textures only differentiated by the different amounts of grunge on them and alternate between those textures on the castle. also that huge clock might look better as a model u know? lil more detail to its sides and u could have an animated shader for the hands. maybe even spin em backwards castlevania style. yeah its a super cool idea and the maps gunna rock. u could really kill with good ambience tho like lightning, wolf howls, random bugs, gargoyle or angel statues, and grungy textures. just some ideas im not knocking it at all im not currently modeling anything atm. im working on maris broods body but its gunna be a minute for her face... so... if u want i can make u some quick map objects thatll add to it like maybe a few different piles of brick and moss, a gargoyle or two, piles of bones, maybe even a cool clock. i could texture em too, or just uv map em and u can texture em to match yer current colors. the bugs would just be animated shaders edit: here i made this in like no time.. want it? u can texture it yerself so it matches if u want heres 4 textures all the same but all with different vines and grunge so u can see what i mean by making it less repetative. and u can just swap between the four so none of the castle appears to be repetative. also, u can use the lighting to kinda blend it all in too even just random bits of clutter like this all these ar just rough draft bs but u should get the ideas im trying to relate. heres an idea... how about if u set triggers in different parts of yer map to trigger different ambient sounds? like if this was a top view of yer map and the white boxes are triggers... anything u need like the gargoyles or maybe some random clutter models like piles of brick and bones just ask. also, maybe instead of just rotating the same tree three times maybe u can have new dead tree models, some different sizes... stumps maybe, etc. also, instead of texturing those stone walls with the mossy wall texture, maybe u can texture em just stone and dirt and put an alpha mapped plane of moss over it spaced a bit so it has some depth to the moss. i like this map idea i did a library wayy back in the day and it was pretty cool so im stoked to see the castle.
