baldur's gate style portraits tutorial

so im new here, as you can probably see, but i've stumbled across this forum multiple times while browsing for nice baldur's gate style portraits. im a fan of the game, obviously, and have beaten it many many times normally, and quite a few times completed some challenges (single character on impossible, single character on impossible without items, no reloading, no reloading no resurrection, etc).
here's the thing, i really like the style of the portraits in baldur's gate (opposed to icewind dale portraits, they are good, but i like baldur's better), and i would like to learn how to make them (if possible). i understand that basically they are made by picking a portrait of someone, get some armor, hair, weapon (maybe) and slap it all together, smudge it a bit with some filters, add some scars maybe and magically you would get a cool baldur's gate style portrait. but im not that good at photoshop, and i have only ever tried once to make something similar (as a joke) and i feel like i would be able to do it if i found a good tutorial for it.
so what im asking is: do any of you guys and girls know of a good tutorial on making baldur's gate style portraits, or even any photoshop tutorial that can help me accomplish something similar at least?
