Bit of help with Photoshop

[beyond the darkness]

Chances are this has been done before but anyway...
If been doing alot of messing around with photoshop, using it to paint my art work but it is just pick colour, fill tool, paint brush repeat untill done.
Can anyone help me with a better way to go about.

Whelp.  I use thel tool to get solid color, and then I do all of my shading with the airbrush tool.  I do fur textures with the smudge tool.  I have the brushes I use for that somewhere on my Deviantart site.

I suppose it depends on what effect you're trying to achieve: Realistic, 'toony, painterly, or a mixnmatch/intermediate of them. I usually do stuff somewhere between realistic/toony, though more to the toony side.
  For reastic/semi-realistic, I'll have many many layers for fur textures, using custom brushes to simluate multiple brush strokes. Shading usually done with airbrush.
  With my usual style, I'll leave the lineart on a single layer, then paint in the colours, usually with only a few layers for flat colours, shadows, highlights etc.
  May I suggest that instead of using the fill tool, you paint in the colours on a layer underneath the lineart? I've found it much easier than eliminating one by one the jaggies/white spots that inevitably appear when using fill. Same result, easier (for me, anyhow) method. Hope that helps. '>
