It looks good, though it could do with some of the functions from DPaint and Grafx2; particularly the shade/qshade modes and opacity.

Offhand, it looks like the main advantage it has over my GIMP setup is the colorizable patterns. I haven't implemented that yet, though i do have the next/prev color facility (and the shading modes and 'indexed' opacity)

Think i'll implement colorizable brushes next.

Actually for pixel art on linux I am switching to mtpaint. I wrote in the forum of pixeljoint, about this. It's a lovely software, for pixel art (using linux), expecially old skool one :)

Yes.  If you know how to recompile stuff, I definitely recommend you get the latest development release 2.3.5. In particular, the improvements relating to pixel art are:

* Using palettes is much much easier
* Curves tool can be controlled entirely via keyboard
* Menu reorganization, things like 'paste as new brush' are more accessible
* RGB->Indexed conversion defaults to no dithering.

I use several plugins I have written to improve the pixel art related functions, allowing eg. to indexize the currently selected area without changing the image mode.

Cool! It reminds me i should do some old-skool style logo sooner or later. I read you are into demo scene pixel art. I were too. Are you using Gimp for pixel art? I use it when i am on linux (like now).
