A humble attempt to reproduce the genius of Adam and his Hellgate to Baator and his creature catalogues.
I would like to bring attention to the use of colour. Both pieces are done is the EGA palette. I really want to learn the technique used in Hellgate at some point.
Nice icons, the classic outfits fit the nostalgic palette as well. I like the fighter guy the best, the pose looks great. I miss a bit of harder shadows under the arm/arrow of the elf, and the anatomy of the mage looks a bit off as well. Here is a quick workflow visualisation of my creature catalogue icons I made for the FRUA boards way back, they might help You as well:
Nice work on the frame too, I particularly like the weapon silhouettes, thought I find the dark cyan and purple bits on the tentacles too light/contrasty: they look more like noise as reflection.
Extra points if you can guess the RPG, which this now vaguely reminds of.
