Ah, no problem. I mostly use Photoshop, but once you learn one, it becomes that much easier to learn the others. I recently made a tutorial of how I create some of my art. Hopefully it helps [link], but what's best is finding a style that fits you . As always, it takes time and practice, lots of it. If there is one specific thing you'd like help on first, then that's fine by me.
Thanks so much. Roughly 10 hours or so. My basic routine is sketch->lineart->base colors->shading. For shading, well I use a combination of things , from small brushes to the burn/dodge tool, color replacement tool, layer properties, and more.
