Hi,
I am very new to pixel art, although i have drawn some tiles and textures in the passed i am not very good at it. Now i desperatly need to improve my skills because i am busy on programming a isometric tile game. I already got the dimensions i need and did a view tiles with photoshop. Not much of painting but more like sticking photoreal textures against my templates and edit/filter them a bit. My mud texture on my 32*16 tile is just a noise, dispeckle, low noise

.
Now i did read a lot passed days and see i don't need many colors for good quality, but is using a 256 color paint program cutting on the quality of 16M colors while still picking just 3,4 or 5 shaded for a color?
Like i said i'm currently using photoshop, but i have seen some video's of people making those isometric lines instantly, and there might be programs that just add more functions that are needed for this isometric pixel art.
However, i'm still going to try for a more or less photoreal approach, jagged alliance style is really what i am looking to make. I still have to study it's palletes a bit but just have been really busy getting my tile engine together.
I also love how you can view your model at 100 or 200% and draw in it zoomed at 1000%.
Anyway, what type of program suits me best? Should i just stick to photoshop which i'm comfortable with or should i get some nice pixel art program.
