The bestiary will most likely group monsters by environment and will be sorted from Ambient through to Minor, Major & Boss class (low to high challenge). The hope is that this organisation will make it easy for GMs to identify an appropriate adversary with minimal fuss. Clustering the creatures by play zone should also give a nice holistic view of each ecosystem.
Boss monsters will have the most complex layout. Maybe illustrated special attacks, strike points and additional forms/mutations. Will be a 3-4 page entry.
Minor & Major will be quite similar to each other in terms of presentation. Depending on the creature it may include a few of the boss layout elements. Prolly 1-2 page entry.
Ambient covers notable flora and fauna. May not even require a stat block and be 1/2 page (or less) entry.
1st spread of Psycho-Armour (boss) Note: Another page with additional info is needed
War Bruun (major)
The War Bruun pages feels a little dull. Maybe a size chart and location map could add a little more visual interest (as well as being useful). Possibly my current typography system is too minimal.
The stat block needs more design love (introducing more of the icons I've developed elsewhere, making it visually distinctive, etc) It should be the main focus of the page, and I rather crudely achieved this by making it a black slab and thus introduced some serious legibility issues (small, light type reversed out of black?! that won't print well either)
The other design choice I'm struggling with is whether the main image should be more technical in nature (side/front elevation) or be more of a flavour/mood illustration. Hmmm.
Note: Drawings are not final representations and are still pretty rough/embryonic (though am quite pleased with chib saddle-helm)
