Next comes the shading on the white parts, such as the gloves, eyes, etc etc. This is simple enough to do, as you only have the shading layer to worry about. Simply select the required areas via Polygon Lasso Tool, and fill away.

That was a waste of time typing...you'll now end up with the lovely image to the left.

NEXT! We now have the lovely task of making teh fire...uh...fire-y. So, what we do is our usual "creation-of-two-new-layers" ritual. One for the darker shade of red, one fer yellow. I used the EyeDropper Tool to get the correct colours, though you can pick your own, if ye wants to.

Firstly colour in the whole fire bit in this shade of red. Done that? Right, again, with our friend, Mr. Polygon Lasso Tool, select the area you don't want, in this case, the central part, and then delete it, making sure you leave a border. Now, FOR THE LOVE OF GOD, DON'T DESELECT.

Fer the yellow bit, colour in the part that is still selected. Done that? Good. Now, as you did with the red part, select the area you don't want (again, leaving a border) and delete it. That should leave you with the white underlay and a pretty schnazzy effect. Add any details you need and you should be here:

If you're about ready to shoot yourself, or collapse like I am, you're almost done. :P Next up, the easiest part. The eyes. Which is ironic considering the eyes on the adventure style are a git to colour...

Create ANOTHER new layer (providing your PC hasn't crashed due to the amount of layers already...) on top of your original lineart. Select a moderately sized round Brush Tool (about enough to cover/overlap about 1/4 of the eye) and then simply dollop a blob on each of them. Then use Mr. Lasso to remove any part that overlaps onto your main lineart.
