[Sombre]

With a slight recolouring of the wings to make them more recognisable the only problem with the second one would be that it doesn't look holy. If you're trying to draw a halo, keep it either a really clear and simple floating gold/white hoop with some shading, or do a brilliant 'awe' style aura around the head using extremely bright white/yellow (keep in mind that if you try to make this fade to black to look good on a black background, it will look rubbish ingame).

You could also give him glowing eyes. Colour the eyes a very bright colour then take a round brush shape with the same colour and drop a series of 10 opacity circles, each smaller than the last, centred on the eye. You can see this effect with one of my slann graphics in the Lizardmen thread.

At your level I would suggest just doing a simple halo and recolouring the wings of #2.
