in source I would've done this with a 3D skyboxWell, you can:
1. Create a large outdoor area with some displacement maps and treelines, and fog to hide the edges. Lets call it carrotjuice .
2. Load the map ingame and turn cheats on ( sv_cheats 1 ).
3. Activate the noclip-mode by simply opening the console and enter "noclip" and hit Enter.
4. Fly to the center of where you want the skybox.
5. Open up the console and type "mat_envmaptgasize 256", hit Enter.
Now type "envmap" and press Enter. Now, 6 TGA-files are now created and saved into a folder named "cubemap_screenshots" in your modfolder ( i.e. for HL2DM: SteamSteamAppsyouraccountHalf-Life 2 Deathmatchhl2mp ).

As far as painting it from scratch, i've never found a program or a trick to do it very well. I seem to remember somebody mentioning a photoshop plugin to help with this, but i could never find it...
